2.Consider an application that transmits data at a steady rate (for example, the sender generates a N-bit units of data every k time units, where k is small and fixed). Also, whe such an application starts, it will stay on for a relatively long period of time. Answer the following questions, briefly justifying your answer:
a. would a packet-switched network or a circuit switched network be more appropriate for this application? why?
b. Suppose that a packet-switching network is used and the only traffic in this network comes from such applications as described above. Furthermore, assume that the sum of the application data rates is less than the capacities of each and every link. Is some form of congestion control needed? why?
