What is a router?

A router is a device for networking which transmits data packets between computer networks. Routers perform Internet traffic steering roles. Data transmitted over the internet, such as a web page or email, is in data packet format. Usually, a packet is transmitted from one router to another router via the networks that make up an internet (e.g. the internet) until it enters the point of departure.

Home and small office routers are the most common type of IP routers that simply forward IP packets between the home computers and the Internet. An example of a router will be the owner's cable or DSL router, which connects to the Internet through an ISP (internet service provider). More sophisticated routers, such as corporate routers, link large business or ISP networks to powerful core routers which forward high-speed data along the Internet backbone's optical fiber lines.

A router links to two or more lines of data from different IP networks. When a data packet enters on one of the lines, the router reads the information in the packet header about the network address to decide the ultimate destination. Instead, using information in its routing table or routing policy, the packet is guided on its journey to the next network.

What is a Router For?

A router is the first safety line from being intruded into a network. Enabling the highest level of router protection turns stuff like the firewall into something, which is the safest way to keep your computer system secure from attack.

Most routers only link via network cables to other network devices, and do not allow drivers to run on Windows or other operating systems. However, routers which link via USB or FireWire to a computer usually require drivers to operate properly.

Many routers are manufactured by companies such as Linksys, 3Com, Belkin, D-Link, Motorola, TRENDnet, and Cisco, but there are a lot more.

How Routers Work?

A router usually connects to the modem via the internet or WAN port via a network cable, and then physically, again via a network cable, to the network interface card in any wired network devices you might have. A wireless router can connect devices which also support the particular standard used by different wireless standards.

Routers link a modem to other devices — like a fiber, cable, or DSL modem — to allow connectivity between those devices and the internet. Many routers, including wireless routers, usually have several network ports to connect through devices simultaneously to the Internet.

Types of routers?

Core routers used by Internet Service Providers (ISPs) are the fastest and most efficient, sitting in the center of the internet and transmitting information along the backbone of the main fibre optic.

An edge router, also known as an access router, is a lower-capacity device that resides at the boundary of a LAN and connects it to a public internet or a private wide area network (WAN) and/or external local area network (LAN).

A wireless router works in the same way as the router in a hard-wired home or business local area network (LAN), but allows greater mobility for notebook or portable computers. A logical router is a designed partition of a normal, or physical, router network hardware. This replicates the functionality of the hardware, generating several routing domains over a single router. Logical routers perform a subset of tasks that the physical router can handle, and each that include several routing instances and routing tables.

Branch routers connect remote office locations of an enterprise to their WAN, which links to the edge routers of the primary campus network. Branch routers also have additional functions, such as multiplexing time-divisions, wireless LAN control capabilities and acceleration of WAN applications.

Router Protocols

Routing protocols decide how a router identifies other network routers, keeps track of all potential destinations, and makes complex decisions about where each network message should be sent to. Common protocols cover:

Interior Gateway Routing Protocol (IGRP) - specifies how routing information inside an autonomous network will be shared between gateways. Certain network protocols will then use the routing information to determine how they will route transmissions.

Open Shortest Path First (OSPF) - used when traveling through a series of linked networks to find the best route for packets. The Internet Technology Task Force (IETF) designates OSPF as one of the IGPs (Inner Gateway Protocols);

Enhanced Protocol on Interior Gateway Routing (EIGRP) - developed from the IGRP. When a router in one of these tables is unable to find a path to a destination, it will ask its neighbors for a path and in turn will ask their neighbors before a route is found. When a routing table entry changes in one of the routers, it notifies its neighbors of the change instead of sending the entire table.

Border Gateway Protocol (BGP) - manages how packets are routed over the Internet by exchanging information among edge routers. BGP provides network stability that ensures that routers can quickly adapt to send packets via another reconnection if one internet path goes downwards.

Routing Information Protocol (RIP) - the original protocol to describe how routers can exchange information when transferring traffic within a local area network interconnected group. The total number of hops allowed for RIP is 15, restricting the size of networks that can be enabled by RIP.

Exterior Gateway Protocol (EGP)- specifies how routing information is shared between two adjacent gateway hosts, each with its own router. EGP is widely used for the sharing of routing table information between internet hosts.
