IP Router Internet Router
Internet router is a router in the Internet that forwards IP packets between local, regional and national providers. It is also called as "IP router."
When a computer communicates with another on the Internet, it addresses each packet with the other computer's IP address and then sends it to the closest Internet router. The router then uses a routing algorithm to send the packet across the Internet to the destination computer.
An Internet router is typically connected to several different networks. An office building often has several routers connecting to various local area networks, found in "wiring closets" on each floor jammed full of network equipment and cables. Each office building typically has one router for connection to the wide area Internet itself.
Some of the important functionalities of IP routers include:
1. Routing Table construction
2. Route Processing
3. Packet Forwarding
4. Packet Translation and
5. Authentication
With the advances made in the design of IP routers, some important open issues still remain to be resolved. These include packet classification and resource provisioning, improved price/performance router designs, “active networking” and ease of configuration, reliability and fault tolerance designs, and Internet billing/pricing.
Extensive work is being carried out both in the research community and industry to address these problems.
