Nokia's headquarters are in Espoo, in the greater Helsinki metropolitan area. In 2017, Nokia employed approximately 102,000 people across over 100 countries, did business in more than 130 countries, and reported annual revenues of around €23 billion. Nokia is a public limited company listed on the Helsinki Stock Exchange and New York Stock Exchange. It is the world's 415th-largest company measured by 2016 revenues according to the Fortune Global 500, having peaked at 85th place in 2009. It is a component of the Euro Stoxx 50 stock market index.\r\nThe company has had various industries in over 150 years. It was founded as a pulp mill and had long been associated with rubber and cables, but since the 1990s focuses on large-scale telecommunications infrastructures, technology development, and licensing. Nokia is a notable major contributor to the mobile telephony industry, having assisted in the development of the GSM, 3G and LTE standards (and currently in 5G), and is best known for having been the largest worldwide vendor of mobile phones and smartphones for a period. After a partnership with Microsoft and market struggles, its mobile phone business was eventually bought by the former, creating Microsoft Mobile as its successor in 2014. After the sale, Nokia began to focus more extensively on its telecommunications infrastructure business and on the Internet of things, marked by the divestiture of its Here mapping division and the acquisition of Alcatel-Lucent, including its Bell Labs research organization. The company then also experimented with virtual reality and digital health, the latter through the purchase of Withings. The Nokia brand has since returned to the mobile and smartphone market through a licensing arrangement with HMD Global. Nokia continues to be a major patent licensor for most large mobile phone vendors. As of 2018 Nokia is the world's third largest network equipment manufacturer.\r\nThe company was viewed with national pride by Finns, as its successful mobile phone business made it by far the largest worldwide company and brand from Finland. At its peak in 2000, during the telecoms bubble, Nokia alone accounted for 4% of the country's GDP, 21% of total exports, and 70% of the Helsinki Stock Exchange market capital.\r\nSource: https://en.wikipedia.org/wiki/Nokia","companyTypes":["supplier","vendor"],"products":{},"vendoredProductsCount":1,"suppliedProductsCount":1,"supplierImplementations":[],"vendorImplementations":[],"userImplementations":[],"userImplementationsCount":0,"supplierImplementationsCount":0,"vendorImplementationsCount":0,"vendorPartnersCount":0,"supplierPartnersCount":0,"b4r":0,"categories":{"37":{"id":37,"title":"PC - personal computer","description":"A personal computer (PC) is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large costly minicomputer and mainframes, time-sharing by many people at the same time is not used with personal computers.\r\nInstitutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with the machines. While personal computer users may develop their own applications, usually these systems run commercial software, free-of-charge software ("freeware"), which is most often proprietary, or free and open-source software, which is provided in "ready-to-run", or binary, form. Software for personal computers is typically developed and distributed independently from the hardware or operating system manufacturers. Many personal computer users no longer need to write their own programs to make any use of a personal computer, although end-user programming is still feasible. This contrasts with mobile systems, where software is often only available through a manufacturer-supported channel, and end-user program development may be discouraged by lack of support by the manufacturer.\r\nSince the early 1990s, Microsoft operating systems and Intel hardware have dominated much of the personal computer market, first with MS-DOS and then with Microsoft Windows. Alternatives to Microsoft's Windows operating systems occupy a minority share of the industry. These include Apple's macOS and free and open-source Unix-like operating systems.\r\nThe advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people in all countries.\r\n"PC" is an initialism for "personal computer". The IBM Personal Computer incorporated the designation in its model name. It is sometimes useful to distinguish personal computers of the "IBM Personal Computer" family from personal computers made by other manufacturers. For example, "PC" is used in contrast with "Mac", an Apple Macintosh computer. Since none of these Apple products were mainframes or time-sharing systems, they were all "personal computers" and not "PC" (brand) computers.","materialsDescription":" <span style=\"font-weight: bold;\">What types of stationary personal computers exist?</span>\r\n<span style=\"font-weight: bold;\">Desktops</span> - refer to the type of stationary PC. From the name it is clear that these are devices that are installed and work on a table and are not transferred during operation. As a rule, representatives of this group are high-performance powerful devices. They consist of a system unit (a rectangular box), to which a monitor, keyboard and mouse are connected.\r\n<span style=\"font-weight: bold;\">Servers</span> - this type of computer has its own specific tasks that it performs remotely or locally in place. The vast majority of servers are quite powerful machines. The appearance of the servers is slightly different from the usual PC - they are mounted in metal racks that look like furniture shelves. The racks themselves are placed in a special room (server room), the necessary temperature regime is necessarily maintained in it.\r\n<span style=\"font-weight: bold;\">Nettops</span> - refer to the type of stationary PC. The system unit is compact in size, usually with low power consumption and noise. Due to the small size, nettops have lower performance, but they fit perfectly into the home environment and do not occupy expensive office space.\r\n<span style=\"font-weight: bold;\">Microcomputers</span> are computers that fit in a miniature enclosure that looks very similar to a flash drive. The microcomputer itself does not have an output device, therefore, through an HDMI connection, it connects to a monitor or TV. Controls, such as a mouse or keyboard, are connected via the built-in USB ports or Bluetooth. Technical specifications depend on the configuration, as with any other PC.\r\n<span style=\"font-weight: bold;\">Monoblocks</span> - refer to the type of stationary PC. The system unit and the monitor are a single unit. Accessories and boards are placed in the compartment, which is mounted on the back of the monitor. It has an aesthetic appearance and does not take up much space.\r\n<span style=\"font-weight: bold;\">What are the types of portable personal computers?</span>\r\nA laptop computer can also be called portable. They differ from desktop dimensions and weight in a smaller direction and more capacious batteries, which is understandable because you need to carry it with you.\r\n<span style=\"font-weight: bold;\">Laptops and netbooks</span> - refer to the type of portable (laptop) PCs, have a battery for offline operation without using a network. The case is made in the form of a clamshell, a screen is installed at the top, and a keyboard at the bottom. Netbooks are smaller than laptops, respectively, have lower performance, although the battery life is longer.\r\n<span style=\"font-weight: bold;\">Tablet laptops</span> - refer to the type of portable (laptop) PC. The case consists of a touch screen display - Touchscreen. Their main purpose is surfing the Internet, watching videos, listening to audio, gaming and other applications. The compact dimensions make this group especially popular for travelers. Tablet laptops have a keyboard that either folds up or extends out of a niche under the screen. In tablets, the touchscreen is the input medium. For this group, battery life is important.\r\n<span style=\"font-weight: bold;\">Pocket PCs and smartphones</span> - belong to the type of portable (laptop) PC. Distinctive features are a small size and a large reserve of battery life. The input tool is either a touch screen or a retractable keyboard.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_PC.png","alias":"pc-personal-computer"},"56":{"id":56,"title":"Router","description":"A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.\r\nA router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey.\r\nThe most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. An example of a router would be the owner's cable or DSL router, which connects to the Internet through an Internet service provider (ISP). More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone.\r\nThe main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address. When a router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the addresses in the routing table. Once a match is found, the packet is encapsulated in the layer-2 data link frame for the outgoing interface indicated in the table entry. A router typically does not look into the packet payload,[citation needed] but only at the layer-3 addresses to make a forwarding decision, plus optionally other information in the header for hints on, for example, quality of service (QoS). For pure IP forwarding, a router is designed to minimize the state information associated with individual packets. Once a packet is forwarded, the router does not retain any historical information about the packet.\r\nThe routing table itself can contain information derived from a variety of sources, such as a default or static routes that are configured manually, or dynamic routing protocols where the router learns routes from other routers. A default route is one that is used to route all traffic whose destination does not otherwise appear in the routing table; this is common – even necessary – in small networks, such as a home or small business where the default route simply sends all non-local traffic to the Internet service provider. The default route can be manually configured (as a static route), or learned by dynamic routing protocols, or be obtained by DHCP.\r\nA router can run more than one routing protocol at a time, particularly if it serves as an autonomous system border router between parts of a network that run different routing protocols; if it does so, then redistribution may be used (usually selectively) to share information between the different protocols running on the same router.\r\nBesides making a decision as to which interface a packet is forwarded to, which is handled primarily via the routing table, a router also has to manage congestion when packets arrive at a rate higher than the router can process. Three policies commonly used in the Internet are tail drop, random early detection (RED), and weighted random early detection (WRED). Tail drop is the simplest and most easily implemented; the router simply drops new incoming packets once the length of the queue exceeds the size of the buffers in the router. RED probabilistically drops datagrams early when the queue exceeds a pre-configured portion of the buffer, until a pre-determined max, when it becomes tail drop. WRED requires a weight on the average queue size to act upon when the traffic is about to exceed the pre-configured size, so that short bursts will not trigger random drops.\r\nAnother function a router performs is to decide which packet should be processed first when multiple queues exist. This is managed through QoS, which is critical when Voice over IP is deployed, so as not to introduce excessive latency.\r\nYet another function a router performs is called policy-based routing where special rules are constructed to override the rules derived from the routing table when a packet forwarding decision is made.\r\nRouter functions may be performed through the same internal paths that the packets travel inside the router. Some of the functions may be performed through an application-specific integrated circuit (ASIC) to avoid overhead of scheduling CPU time to process the packets. Others may have to be performed through the CPU as these packets need special attention that cannot be handled by an ASIC.","materialsDescription":" <span style=\"font-weight: bold;\">What Is a Router?</span>\r\nRouters are the nodes that make up a computer network like the internet. The router you use at home is the central node of your home network.\r\nIt functions as an information manager between the internet and all devices that go online (i.e. all devices connected to the router). Generally speaking, routers direct incoming traffic to its destination.\r\nThis also makes your router the first line of security in protecting your home network from malicious online attacks.\r\n<span style=\"font-weight: bold;\">What Does a Router Do?</span>\r\nYour router handles network traffic. For example, to view this article, data packages coding for this website have to transit from our server, through various nodes on the internet, and finally through your router to arrive on your phone or computer. On your device, your browser decodes those data packages to display the article you’re currently reading.\r\nSince a typical household has more than one device that connects to the internet, you need a router to manage the incoming network signals. In other words, your router makes sure that the data packages coding for a website you want to view on your computer aren’t sent to your phone. It does that by using your device’s MAC address.\r\nWhile your router has a unique (external) IP address to receive data packages from servers worldwide, every device on your home network also carries a unique MAC address. Simply put, when you try to access information online, your router maintains a table to keep track of which device requested information from where. Based on this table, your router distributes incoming data packages to the correct recipient.\r\n<span style=\"font-weight: bold;\">What Is the Difference Between Modems and Routers?</span>\r\nA modem turns the proprietary network signal of your ISP (internet service provider) into a standard network signal. In theory, you can choose between multiple ISPs and some of them may use the same delivery route. Your modem knows which signals to read and translate.\r\nThe kind of modem your ISP will provide you with depends on how you’re connecting to the internet. For example, a DSL modem requires a different technology than a cable or fiber optic broadband modem. That’s because one uses the copper wiring of your telephone line, while the others use a coaxial or a fiber optic cable, respectively.\r\nThe DSL modem has to filter and read both the low frequencies that phone and voice data produce, as well as the high frequencies of internet data. Cable modems, on the other hand, have to differentiate between television and internet signals, which are transmitted on different channels, rather than different frequencies. Finally, fiber optic uses pulses of light to transmit information. The modem has to decode these signals into standard data packages.\r\nOnce the modem has turned the ISP’s network signal into data packages, the router can distribute them to the target device.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Router1.png","alias":"router"},"178":{"id":178,"title":"IoT - Internet of Things","description":"The Internet of things (IoT) is the extension of Internet connectivity into physical devices and everyday objects. Embedded with electronics, Internet connectivity, and other forms of hardware (such as sensors), these devices can communicate and interact with others over the Internet, and they can be remotely monitored and controlled.\r\nThe definition of the Internet of things has evolved due to the convergence of multiple technologies, real-time analytics, machine learning, commodity sensors, and embedded systems. Traditional fields of embedded systems, wireless sensor networks, control systems, automation (including home and building automation). and others all contribute to enabling the Internet of things. In the consumer market, IoT technology is most synonymous with products pertaining to the concept of the "smart home", covering devices and appliances (such as lighting fixtures, thermostats, home security systems and cameras, and other home appliances) that support one or more common ecosystems, and can be controlled via devices associated with that ecosystem, such as smartphones and smart speakers.\r\nThe IoT concept has faced prominent criticism, especially in regards to privacy and security concerns related to these devices and their intention of pervasive presence.","materialsDescription":"<span style=\"font-weight: bold;\">What is the Internet of Things (IoT)?</span>\r\nThe Internet of things refers to the network of things (physical objects) that can be connected to the Internet to collect and share data without human-to-human or human-to-computer interaction.\r\n<span style=\"font-weight: bold;\">Why is it called the Internet of Things?</span>\r\nThe term Internet of things was coined by Kevin Ashton in 1999. Stemming from Kevin Ashton’s experience with RFID, the term Internet of things originally described the concept of tagging every object in a person’s life with machine-readable codes. This would allow computers to easily manage and inventory all of these things.\r\nThe term IoT today has evolved to a much broader prospect. It now encompasses ubiquitous connectivity, devices, sensors, analytics, machine learning, and many other technologies.\r\n<span style=\"font-weight: bold;\">What is an IoT solution?</span>\r\nAn IoT solution is a combination of devices or other data sources, outfitted with sensors and Internet connected hardware to securely report information back to an IoT platform. This information is often a physical metric which can help users answer a question or solve a specific problem.\r\n<span style=\"font-weight: bold;\">What is an IoT Proof of Concept (PoC)?</span>\r\nThe purpose of a PoC is to experiment with a solution in your environment, collect data, and evaluate performance from a set timeline on a set budget.

If we think of the computer system as a layered model, the system software is the interface between the hardware and user applications. The operating system (OS) is the best-known example of system software. The OS manages all the other programs on a computer.\r\nOther examples of system software include:\r\n<ul><li>The BIOS (basic input/output system) gets the computer system started after you turn it on and manages the data flow between the operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.</li><li>The boot program loads the operating system into the computer's main memory or random access memory (RAM).</li><li>An assembler takes basic computer instructions and converts them into a pattern of bits that the computer's processor can use to perform its basic operations.</li><li>A device driver controls a particular type of device that is attached to your computers, such as a keyboard or a mouse. The driver program converts the more general input/output instructions of the operating system to messages that the device type can understand.</li></ul>\r\nAdditionally, system software can also include system utilities, such as the disk defragmenter and System Restore, and development tools, such as compilers and debuggers.\r\nSystem software and application programs are the two main types of computer software. Unlike system software, an application program (often just called an application or app) performs a particular function for the user. Examples include browsers, email clients, word processors, and spreadsheets.","materialsDescription":" \r\n<span style=\"font-weight: bold; \">What is system software?</span>\r\nSystem software is software designed to provide a platform for other software. Examples of system software include operating systems like macOS, GNU/Linux and Microsoft Windows, computational science software, game engines, industrial automation, and software as a service applications.\r\nIn contrast to system software, software that allows users to do user-oriented tasks such as create text documents, play games, listen to music, or browse the web are collectively referred to as application software.\r\nIn the early days of computing most application software was custom-written by computer users to fit their specific hardware and requirements. In contrast, system software was usually supplied by the manufacturer of the computer hardware and was intended to be used by most or all users of that system.\r\nThe line where the distinction should be drawn is not always clear. Many operating systems bundle[jargon] application software. Such software is not considered system software when it can be uninstalled usually without affecting the functioning of other software. Exceptions could be e.g. web browsers such as Internet Explorer where Microsoft argued in court that it was system software that could not be uninstalled. Later examples are Chrome OS and Firefox OS where the browser functions as the only user interface and the only way to run programs (and other web browsers can not be installed in their place), then they can well be argued to be (part of) the operating system and hence system software.\r\nAnother borderline example is cloud-based software. This software provides services to a software client (usually a web browser or a JavaScript application running in the web browser), not to the user directly, and is therefore systems software. It is also developed using system programming methodologies and systems programming languages. Yet from the perspective of functionality there is little difference between a word processing application and word processing web application.\r\n<span style=\"font-weight: bold; \">Operating systems or system control program</span>\r\nThe operating system (prominent examples being Microsoft Windows, macOS, Linux, and z/OS), allows the parts of a computer to work together by performing tasks like transferring data between memory and disks or rendering output onto a display device. It provides a platform (hardware abstraction layer) to run high-level system software and application software.\r\nA kernel is the core part of the operating system that defines an API for applications programs (including some system software) and an interface to device drivers.\r\nDevice drivers, including also computer BIOS and device firmware, provide basic functionality to operate and control the hardware connected to or built into the computer.\r\nA user interface "allows users to interact with a computer." Either a command-line interface (CLI) or, since the 1980s a graphical user interface (GUI). Since this is the part of the operating system the user directly interacts with, it may be considered an application and therefore not system software.\r\n<span style=\"font-weight: bold;\">Utility software or system support programs</span>\r\nFor historical reasons, some organizations use the term systems programmer to describe a job function which is more accurately termed systems administrator. Software tools these employees use are then called system software. This so-called Utility software helps to analyze, configure, optimize and maintain the computer, such as virus protection. In some publications, the term system software also includes software development tools (like a compiler, linker or debugger).","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_System_and_Network_Management_Software.png","alias":"system-software"},"513":{"id":513,"title":"Networking","description":" Networking hardware, also known as network equipment or computer networking devices, are electronic devices which are required for communication and interaction between devices on a computer network.

Wireless networking has become increasingly popular, especially for portable and handheld devices.\r\nOther networking hardware used in computers includes data center equipment (such as file servers, database servers and storage areas), network services (such as DNS, DHCP, email, etc.) as well as devices which assure content delivery.\r\nTaking a wider view, mobile phones, tablet computers and devices associated with the internet of things may also be considered networking hardware. As technology advances and IP-based networks are integrated into building infrastructure and household utilities, network hardware will become an ambiguous term owing to the vastly increasing number of network capable endpoints.","materialsDescription":" <span style=\"font-weight: bold;\">What is network equipment?</span>\r\nNetwork equipment - devices necessary for the operation of a computer network, for example: a router, switch, hub, patch panel, etc. You can distinguish between active and passive network equipment.\r\n<span style=\"font-weight: bold;\">What is an active network equipment?</span>\r\nActive networking equipment is equipment followed by some “smart” feature.

Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.\r\nA router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey.\r\nThe most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. An example of a router would be the owner's cable or DSL router, which connects to the Internet through an Internet service provider (ISP). More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone.\r\nThe main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address. When a router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the addresses in the routing table. Once a match is found, the packet is encapsulated in the layer-2 data link frame for the outgoing interface indicated in the table entry. A router typically does not look into the packet payload,[citation needed] but only at the layer-3 addresses to make a forwarding decision, plus optionally other information in the header for hints on, for example, quality of service (QoS). For pure IP forwarding, a router is designed to minimize the state information associated with individual packets. Once a packet is forwarded, the router does not retain any historical information about the packet.\r\nThe routing table itself can contain information derived from a variety of sources, such as a default or static routes that are configured manually, or dynamic routing protocols where the router learns routes from other routers. A default route is one that is used to route all traffic whose destination does not otherwise appear in the routing table; this is common – even necessary – in small networks, such as a home or small business where the default route simply sends all non-local traffic to the Internet service provider. The default route can be manually configured (as a static route), or learned by dynamic routing protocols, or be obtained by DHCP.\r\nA router can run more than one routing protocol at a time, particularly if it serves as an autonomous system border router between parts of a network that run different routing protocols; if it does so, then redistribution may be used (usually selectively) to share information between the different protocols running on the same router.\r\nBesides making a decision as to which interface a packet is forwarded to, which is handled primarily via the routing table, a router also has to manage congestion when packets arrive at a rate higher than the router can process. Three policies commonly used in the Internet are tail drop, random early detection (RED), and weighted random early detection (WRED). Tail drop is the simplest and most easily implemented; the router simply drops new incoming packets once the length of the queue exceeds the size of the buffers in the router. RED probabilistically drops datagrams early when the queue exceeds a pre-configured portion of the buffer, until a pre-determined max, when it becomes tail drop. WRED requires a weight on the average queue size to act upon when the traffic is about to exceed the pre-configured size, so that short bursts will not trigger random drops.\r\nAnother function a router performs is to decide which packet should be processed first when multiple queues exist. This is managed through QoS, which is critical when Voice over IP is deployed, so as not to introduce excessive latency.\r\nYet another function a router performs is called policy-based routing where special rules are constructed to override the rules derived from the routing table when a packet forwarding decision is made.\r\nRouter functions may be performed through the same internal paths that the packets travel inside the router. Some of the functions may be performed through an application-specific integrated circuit (ASIC) to avoid overhead of scheduling CPU time to process the packets. Others may have to be performed through the CPU as these packets need special attention that cannot be handled by an ASIC.","materialsDescription":" <span style=\"font-weight: bold;\">What Is a Router?</span>\r\nRouters are the nodes that make up a computer network like the internet. The router you use at home is the central node of your home network.\r\nIt functions as an information manager between the internet and all devices that go online (i.e. all devices connected to the router). Generally speaking, routers direct incoming traffic to its destination.\r\nThis also makes your router the first line of security in protecting your home network from malicious online attacks.\r\n<span style=\"font-weight: bold;\">What Does a Router Do?</span>\r\nYour router handles network traffic. For example, to view this article, data packages coding for this website have to transit from our server, through various nodes on the internet, and finally through your router to arrive on your phone or computer. On your device, your browser decodes those data packages to display the article you’re currently reading.\r\nSince a typical household has more than one device that connects to the internet, you need a router to manage the incoming network signals. In other words, your router makes sure that the data packages coding for a website you want to view on your computer aren’t sent to your phone. It does that by using your device’s MAC address.\r\nWhile your router has a unique (external) IP address to receive data packages from servers worldwide, every device on your home network also carries a unique MAC address. Simply put, when you try to access information online, your router maintains a table to keep track of which device requested information from where. Based on this table, your router distributes incoming data packages to the correct recipient.\r\n<span style=\"font-weight: bold;\">What Is the Difference Between Modems and Routers?</span>\r\nA modem turns the proprietary network signal of your ISP (internet service provider) into a standard network signal. In theory, you can choose between multiple ISPs and some of them may use the same delivery route. Your modem knows which signals to read and translate.\r\nThe kind of modem your ISP will provide you with depends on how you’re connecting to the internet. For example, a DSL modem requires a different technology than a cable or fiber optic broadband modem. That’s because one uses the copper wiring of your telephone line, while the others use a coaxial or a fiber optic cable, respectively.\r\nThe DSL modem has to filter and read both the low frequencies that phone and voice data produce, as well as the high frequencies of internet data. Cable modems, on the other hand, have to differentiate between television and internet signals, which are transmitted on different channels, rather than different frequencies. Finally, fiber optic uses pulses of light to transmit information. The modem has to decode these signals into standard data packages.\r\nOnce the modem has turned the ISP’s network signal into data packages, the router can distribute them to the target device.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Router1.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]}],"suppliedProducts":[{"id":3199,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/Nokia_7750_SR-e.jpg","logo":true,"scheme":false,"title":"Nokia 7750 SR-e","vendorVerified":0,"rating":"1.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"nokia-7750-sr-e","companyTitle":"Nokia","companyTypes":["supplier","vendor"],"companyId":5097,"companyAlias":"nokia","description":"<p>The Nokia 7750 SR-e series of IP routers deliver high performance, comprehensive features and resiliency.

Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.\r\nA router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey.\r\nThe most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. An example of a router would be the owner's cable or DSL router, which connects to the Internet through an Internet service provider (ISP). More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone.\r\nThe main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address. When a router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the addresses in the routing table. Once a match is found, the packet is encapsulated in the layer-2 data link frame for the outgoing interface indicated in the table entry. A router typically does not look into the packet payload,[citation needed] but only at the layer-3 addresses to make a forwarding decision, plus optionally other information in the header for hints on, for example, quality of service (QoS). For pure IP forwarding, a router is designed to minimize the state information associated with individual packets. Once a packet is forwarded, the router does not retain any historical information about the packet.\r\nThe routing table itself can contain information derived from a variety of sources, such as a default or static routes that are configured manually, or dynamic routing protocols where the router learns routes from other routers. A default route is one that is used to route all traffic whose destination does not otherwise appear in the routing table; this is common – even necessary – in small networks, such as a home or small business where the default route simply sends all non-local traffic to the Internet service provider. The default route can be manually configured (as a static route), or learned by dynamic routing protocols, or be obtained by DHCP.\r\nA router can run more than one routing protocol at a time, particularly if it serves as an autonomous system border router between parts of a network that run different routing protocols; if it does so, then redistribution may be used (usually selectively) to share information between the different protocols running on the same router.\r\nBesides making a decision as to which interface a packet is forwarded to, which is handled primarily via the routing table, a router also has to manage congestion when packets arrive at a rate higher than the router can process. Three policies commonly used in the Internet are tail drop, random early detection (RED), and weighted random early detection (WRED). Tail drop is the simplest and most easily implemented; the router simply drops new incoming packets once the length of the queue exceeds the size of the buffers in the router. RED probabilistically drops datagrams early when the queue exceeds a pre-configured portion of the buffer, until a pre-determined max, when it becomes tail drop. WRED requires a weight on the average queue size to act upon when the traffic is about to exceed the pre-configured size, so that short bursts will not trigger random drops.\r\nAnother function a router performs is to decide which packet should be processed first when multiple queues exist. This is managed through QoS, which is critical when Voice over IP is deployed, so as not to introduce excessive latency.\r\nYet another function a router performs is called policy-based routing where special rules are constructed to override the rules derived from the routing table when a packet forwarding decision is made.\r\nRouter functions may be performed through the same internal paths that the packets travel inside the router. Some of the functions may be performed through an application-specific integrated circuit (ASIC) to avoid overhead of scheduling CPU time to process the packets. Others may have to be performed through the CPU as these packets need special attention that cannot be handled by an ASIC.","materialsDescription":" <span style=\"font-weight: bold;\">What Is a Router?</span>\r\nRouters are the nodes that make up a computer network like the internet. The router you use at home is the central node of your home network.\r\nIt functions as an information manager between the internet and all devices that go online (i.e. all devices connected to the router). Generally speaking, routers direct incoming traffic to its destination.\r\nThis also makes your router the first line of security in protecting your home network from malicious online attacks.\r\n<span style=\"font-weight: bold;\">What Does a Router Do?</span>\r\nYour router handles network traffic. For example, to view this article, data packages coding for this website have to transit from our server, through various nodes on the internet, and finally through your router to arrive on your phone or computer. On your device, your browser decodes those data packages to display the article you’re currently reading.\r\nSince a typical household has more than one device that connects to the internet, you need a router to manage the incoming network signals. In other words, your router makes sure that the data packages coding for a website you want to view on your computer aren’t sent to your phone. It does that by using your device’s MAC address.\r\nWhile your router has a unique (external) IP address to receive data packages from servers worldwide, every device on your home network also carries a unique MAC address. Simply put, when you try to access information online, your router maintains a table to keep track of which device requested information from where. Based on this table, your router distributes incoming data packages to the correct recipient.\r\n<span style=\"font-weight: bold;\">What Is the Difference Between Modems and Routers?</span>\r\nA modem turns the proprietary network signal of your ISP (internet service provider) into a standard network signal. In theory, you can choose between multiple ISPs and some of them may use the same delivery route. Your modem knows which signals to read and translate.\r\nThe kind of modem your ISP will provide you with depends on how you’re connecting to the internet. For example, a DSL modem requires a different technology than a cable or fiber optic broadband modem. That’s because one uses the copper wiring of your telephone line, while the others use a coaxial or a fiber optic cable, respectively.\r\nThe DSL modem has to filter and read both the low frequencies that phone and voice data produce, as well as the high frequencies of internet data. Cable modems, on the other hand, have to differentiate between television and internet signals, which are transmitted on different channels, rather than different frequencies. Finally, fiber optic uses pulses of light to transmit information. The modem has to decode these signals into standard data packages.\r\nOnce the modem has turned the ISP’s network signal into data packages, the router can distribute them to the target device.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Router1.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]}],"partnershipProgramme":null}},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"implementations":{"implementationsByAlias":{},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"agreements":{"agreementById":{},"ids":{},"links":{},"meta":{},"loading":false,"error":null},"comparison":{"loading":false,"error":false,"templatesById":{},"comparisonByTemplateId":{},"products":[],"selectedTemplateId":null},"presentation":{"type":null,"company":{},"products":[],"partners":[],"formData":{},"dataLoading":false,"dataError":false,"loading":false,"error":false},"catalogsGlobal":{"subMenuItemTitle":""}}
