1.1 Routing When an in reckonent mesh topologys or tangencys are connected to clean up internet work or large electronic network the interconnectedness imposture (c on the wholeed roadwayr) route or faulting the packet to their ultimately destination. The routing is defined as the process performed by a router to come across the next hop of the datagram. Routing protocol is used to continually modify the routing shelves that are consulted for send oning and routing. 1.2 Goal of Routing Algorithm Rapid and consummate pitch shot of packets. Adaptability to changes in network topology resulting from customer or link failures. Adaptability to varying source-destination traffic loads. Ability to route packets away from temporarily congested links. Ability to determine the connectivity of the network. belittled overhead. 1.3 Classification of Routing Algorithm static routing a program computes and installs routes when a packet switch boots; th e routes do not change (simplicity, paltry network overhead.) . Dynamic routing a program builds an initial routing control panel when a packet switch boots; The program then alters the table as conditions in the network Change. Centralized routing a network control center computes all routing paths. Distributed routing routers cooperate by instrument of message exchanges and perform.

Their own routing nurture scale better than centralise routing but are more likely to produce inconsistent results. 1.4 Routing Decision: A routing decisiveness can be make On a per packet can datagram. During the connection s etup time virtual-circuit packet switching,! the path is unconquerable during the connection setup phase. The main ingredients of a good routing algorithmic program depend on the objective function that one is try to optimize. 1.5 Routing shelve Routing table contains information a router needs to route the packets. Router is an internetworking eddy that attached to two or more network and introductory packets from one network to another network.
