Consider an application that transmits data at a steady rate (for example, the sender generates an N-bit unit of data every k unites of time, where k is sand fixed). Also, when such an application starts, it will continue running 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 a packet-switched network is used and the only traffic in this network comes from applications like that describe above. Furthermore, assume that sum of the application data rates is less than the capacities of each and every link. Is some form of congestion control needed? Why? What advantages does packet switching have over circuit switching
