In this article we will discuss Routers Interconnect Networks, will make brief discussion on Routers Interconnect Networks, In last article we discuss about Packet Forwarding Mechanisms.
Most users are unaware of the presence of numerous routers on their own network or on the Internet. Users expect to be able to access web pages, send emails, and download music, regardless of whether the server accessed is on their own network or on another network.
Networking professionals know that it is the router that is responsible for forwarding packets from network to network, from the original source to the final destination.
A router connects multiple networks, which means that it has multiple interfaces that each belong to a different IP network. When a router receives an IP packet on one interface, it determines which interface to use to forward the packet to the destination. The interface that the router uses to forward the packet may be the final destination, or it may be a network connected to another router that is used to reach the destination network.
R1 and R2 are responsible for receiving the packet on one network and forwarding the packet out another network toward the destination network.
Each network that a router connects to typically requires a separate interface. These interfaces are used to connect a combination of both local-area networks (LANs) and wide-area networks (WANs). LANs are commonly Ethernet networks that contain devices, such as PCs, printers, and servers. WANs are used to connect networks over a large geographical area. For example, a WAN connection is commonly used to connect a LAN to the Internet service provider (ISP) network.
Even the Home Office requires a router. The router located at the Home Office is a specialized device that performs multiple services for the home network.
