### Network Routing Problem#### Network Diagram:The diagram represents a network of interconnected nodes labeled A, B, C, D, E, and F. The connections between these nodes have associated numerical values indicating the cost or distance of the link:- A to B: 5- A to D: 3- B to C: 1- B to E: 1- C to D: 2- C to F: 3- E to F: 4#### Problem Statement:Consider the network running a distance-vector routing algorithm that has reached convergence. If the link between nodes B and C fails, answer the following:a) Provide the routing tables at nodes A and D after nodes B and C have reported the link failure.b) Provide the routing tables at nodes A and D after their next mutual exchange of routing information.This setup challenges the concepts of network convergence, link failure handling, and routing table updates using distance-vector algorithms.

Given network diagram contains 6 nodes that are A, B, C, D, E, F. The weighted edges are present between the vertices. Distance vector routing algorithm shares the routing table with the adjacent nodes. That routing table contains node, distance and next nodes.a) The resultant routing table at A after the nodes B and C shared their routing tables is: Node Distance Next node A 0 A B 5 B C 5 D D 3 D E 6 B F 8 D The resultant routing table at D after the nodes B and C shared their routing tables is: Node Distance Next node A 3 A B 3 C C 2 C D 0 D E 4 C F 5 Cb) The resultant routing table at A after mutual exchange of A and D routing table is: Node Distance Next node A 0 A B 5 B C 5 D D 3 D E infinite - F infinite - The resultant routing table at D after mutual exchange of A and D routing table is: Node Distance Next node A 3 A B 8 A C 2 C D 0 D E infinite - F infinite - The distances for nodes E, F are infinite because these two are not adjacent nodes of A, D. So, their distances are not present in both tables until remaining routing tables are shared.

Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.

Question

### Network Routing Problem

#### Network Diagram:
The diagram represents a network of interconnected nodes labeled A, B, C, D, E, and F. The connections between these nodes have associated numerical values indicating the cost or distance of the link:

- A to B: 5
- A to D: 3
- B to C: 1
- B to E: 1
- C to D: 2
- C to F: 3
- E to F: 4

#### Problem Statement:
Consider the network running a distance-vector routing algorithm that has reached convergence. If the link between nodes B and C fails, answer the following:

a) Provide the routing tables at nodes A and D after nodes B and C have reported the link failure.

b) Provide the routing tables at nodes A and D after their next mutual exchange of routing information.

This setup challenges the concepts of network convergence, link failure handling, and routing table updates using distance-vector algorithms.

P7. Examine the network fragment below. w and y are x's only neighbours. W's minimum-cost route to u (not illustrated) is 5, while y's is 6. The pathways from w and y to u and between them are not indicated. All network link costs are positive integers. 2, Give x's distance vector to w, y, and u.
4. a) Consider designing an ATM network with a leaky-bucket policer that ensures a virtual circuit does not send more cells than expected. Suppose a link has a first-in-first-out (FIFO) queue and carries traffic for two virtual circuits. The traffic on the first virtual circuit follows a leaky- bucket policer (with a bucket depth of 9 cells and a token rate of 100 cells/second) and can settle for best-effort service. The traffic on the second virtual circuit follows a leaky-bucket policer (with a bucket depth of one cell and a token rate of 100 cells/second) that cannot tolerate more than 100 milliseconds of delay in delivering each cell. Suppose the propagation delay on the link is 50 milliseconds. Analyse the smallest transmission rate R, in cells per second, that can satisfy the delay constraint, given that the link serves cells in FIFO order.
