1.	Write About The Parts Available In Routing Algorithm?
Answer» Routing ALGORITHM has two parts: It MUST make DECISIONS that determine the route TAKEN by each packet as it travels through the network. In circuit-switched network layers such as X.25 and frame relay networks such as ATM the route is determined whenever a virtual circuit or connection is established. In packet-switched network layers such as IP it is determined separately for each packet, and the algorithm must be particularly simple and EFFICIENT if it is not to degrade network performance. It must dynamically update its knowledge of the network based on traffic monitoring and the detection of configuration changes or failures. This activity is less time-critical; slower and more computation-intensive techniques can be used. Routing algorithm has two parts:
