Question
Consider an application that transmits data at a steady rate (e.g., the sender generates an N-bit unit of data every k time units, where k is small and 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: Would a packet-switched network or a circuit-switched network be more appropriate for this application? Why? Suppose that a packet-switched network is used and the only traffic in this network comes from such applications 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?Explanation / Answer
1.) Since an application is transmitting data for a very long time then it would be better to have a circuit switched network if possible. Since, N-bit data is generated at very small interval of time therefore in order to cope up with transmitting rate, circuit switch would be better choice.
2.) It depends that reciever is able to cope up with the sender's speed. If it can handle that much data rate then there is no need of congestion as only traffic in this network come from given device.
