Question: Consider an application that sends a chunk of data (say, N bits) every k time units where k is some small quantity. When this application

Consider an application that sends a chunk of data (say, N bits) every k time units where k is some small quantity. When this application begins, it always runs for a very long period of time. You may assume that the number of clients receiving this data is small and does not change, and each client is receiving an equal and large amount of data over the execution of the application.

Answer the following questions and briefly justify your answers. Different answers are possible, but a clear justification must be provided.

(a) Which would be more appropriate for this application: A packet-switched network or a circuit-switched network?

(b) For this part, assume that a packet-switched network is used and the only traffic in the network is from applications like the one just described. Also, assume that the sum of the application data rates is less than the capacities of each link in the network.
