Question
Chapter 5, Problem P5P
Program Plan Intro
Distance
In data network, the distance vector algorithm 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.

P5. Consider the network shown below, and assume that each node initially knows the costs to each of its neighbors. Consider the distance-vector algorithm and show the distance table entries at node z. The resulting answer should replicate the technique used in Fig 5.6, though it will vary slightly as there are more than three variables in this specific problem.
In a network of N nodes, how many iterations are required for Dijkstra's algorithm to completes its
execution.
Hint: Section 5.2.1 has the pseudo code for Dijkstra's link state algorithm that finds the shortest
path from a source node to every node in the network. Professor Kurose shows the pseudo code in
his video. The pseudo code in the text shows an initialization step and then a loop. How many
times would the loop be executed for a network of N nodes?
O N+1 times
ON-1 times
ON times
O N² times
Use the provided data to create the Dijkstra Shortest Weighted Path method.Precondition: S is a node in the weighted (directed or undirected) network G.Post-cond: specifies the shortest weighted route between each node of G and s, and d specifies the lengths of those paths.
