Chapter 5, Problem P9P
Program Plan Intro
Distance
In data network, the distance vector routing protocol determines the best route for data packets calculated based on the distance. The distance is measured by the number of routers a packet has to pass. The exchange of information with one another helps to determine the best route across the network.

Students have asked these similar questions
Consider the count-to-infinity issue in the distance vector routing. Can the count-to-infinity issue arise if the cost of a connection is reduced? Why? How about connecting two nodes that have no link?
Provide a brief description of the distance – vector algorithm as used for routing. For the following network, indicate node “C” learns when it gets the initial distance vector from node A , and then the initial distance vector from node B and then the initial distance vector from node D. What does C’s routing table look like at that point?
How precisely does the routing work? Could you provide any clarification on the distance vector routing?
