Question

Two network characteristics influence the performance seen by client-server systems: the network latency = the time it takes for the first bit transmitted to traverse the network from the client to the server (measured in seconds), and the bandwidth = the rate at which data can be transmitted (measured in bits/second.) a) Give an example of a network which exhibits high delay (latency) and also high bandwidth. Explain your answer. b) Now give an example of a network which exhibits low latency and low bandwidth. Explain.

Explanation / Answer

A transcontinental fiber link might have many gigabits/sec of bandwidth, but the latency will also be high due to the speed of light propogation over thousands of kilometers. In contrast, a 56-kbps modem calling a computer in the same building will have a low bandwidth and low latency
