On a p-node linear array there are two packets at each node to begin with. Assume p is even. Packets at node 1 are destined for node + 1, packets at node 2 are destined for + 2, and so on. Let each packet take the shortest path from its origin to its destination. Compute the routing time for this problem under the following priority schemes: farthest origin first, farthest destination first, FIFO, and LIFO.

In the congestion control method of TCP we are having a connection between nodes A and node B which is called connection X. There is another TCP connection between node C and node D which is called connection Y. The initial threshold window size for connection X is 20 KB and for Y is 16 KB. Both the connections X, Y are working independently and follow the Additive increase multiplicative decrease algorithm (AIMD) for congestion control with a maximum segment size of 2 KB. The first timeout occurs at the fifth transmission in connection X and at the sixth transmission in connection Y. After every third transmission from timeout, you again encounter the timeout in both X and Y. At which transmission the connection Y reaches to the same threshold value of the connection X for the first time.
