Question
P3. Consider an application that transmits data at a steady rate (for example, 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: a. Would a packet-switched network or a circuit-switched network be more appropriate for this application? Why? b. Suppose that a packet-switched network is used and the only traffic in this network comes from such applications as described above. Further- more, 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
a.) As per my understanding, a circuit-switched network is more appropriate for this application as it is running for a long period of time. In addition to that, data is generated very frequently.
b.) Since sum of the application data rates is less than the capacities of each and every link, no congestion control mechanism is needed as data transmission and flow will be done smoothly.
Hope it helps, feel free to comment in case of doubt.
