1. (20 points) 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 each node iteration by iteration until the algorithm converges at all nodes. 10 Iteration 0 Iteration 1 Iteration 2 Iteration n (trust me, n won't be crazily too large)
1. (8 pts) Consider a network with the following topology. Unless indicated otherwise, all links have distance = 1. (a) Use the first four steps of using the Dijkistra shortest path algorithm to find the shortest paths from A to the rest of the nodes. (b) Let's assume the distance vector routing algorithm is used. At t = 0, each node only knows the distances to its neighbors. The distances to the other nodes will be set to infinity. Nodes...

Each row in the table corresponds to one iteration of the algorithm, and each column is a pair (D (A), H(A)) where D,(A) is the cost from node i to A and Hi(A) is the next hop on the path from i to...
Distance vector routing In the illustrated network, routes are determined using the distance vector algorithm . The marked router v has been newly added, it only knows the direct costs to its neighbor routers u , y and z . (a) Specify the distance vectors in all routers except v before adding v . We assume that the distance vector algorithm for all routers existing at this time is already terminated. (b) Give the initial distance vector in the router...
Consider the network shown below. Use Dijkstra's algorithm to find the shortest paths from node a to all other nodes. Enter your answers in the a shortest path answers in the following format: node-node-node. For example, if the ssignment link. Enter the shortest path from a to c is through node b, you would enter the answer as: a-b-c 3 5 6 6

Problem 5. Distance Vector (DV) Routing (12 pt.) Consider the network in the LS problem. Assume all the nodes other than the source node have the optimal distance information to all other nodes. Calculate the distance from the source to the destination node, and determine the next hop node. In case of a tie, you can choose any of the best nodes (Hint: “Bellman-Ford example”) (i) dw(s) (ii) dw(t) (iii) dw(y)
1.0. Suppose the network is as follows, where distance-vector routing update is used. Each link has cost 1, and each router has entries in its forwarding table only for its immediate neighbors (so A’s table contains 〈B,B,1〉, 〈D,D,1〉 and B’s table contains 〈A,A,1〉, 〈C,C,1〉). (a). Suppose each node creates a report from its initial configuration and sends that to each of its neighbors. What will each node’s forwarding table be after this set of exchanges? The exchanges, in other words,...
