Whаt the fоur type оf delаys, which cоntribute to the overаll 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 1000 Bytes in one packet to Host B. There is two routers between the two hosts. The distance between any host/router and the router/host is 5 Km, and the rate on both links are 10 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.
