What the four type of delays, which contribute to the overall latency experienced when data travels across a network. Based on the following facts, calculate each of them. If any type of delay cannot be determined, clearly state so in your answer and give the reason why. Host A sends 2000 Bytes in one packet to Host B. There is three routers between the two hosts. The distance between any host/router and the router/host is 20 Km, and the rate on all links are 100 Mbps. Usually, the propagation speed depends on the physical medium of the link, which is equal to, or a little less than, the speed of light. In here, it is 2*108 meters/sec. Assume an ideal router that does not cost any time to move bits from the incoming port to the outgoing port.

Consider the rdt 2.2 sender and receiver below, with FSM transitions labeled in red. Which of the following sequences of transitions could NOT possibly occur as a result of an initial rdt_send() call at the sender (with no messages initially in the channel)? Choose all applicable answers and briefly explain why you think they are not possible to occur.    1) S0, R0, S1, R1, S1 S0, R0, S2, R2, S3 S0, R0, S1, R3, S1 S0, R0, S2, S3, R2, S4   2)       Explanation:
