# How to calculate file distribution time of following example?

Consider distributing a file of size F = 10 Gb to N peers. The server has an upload rate of Us = 20 Mbps, and each peer has a download rate of Di = 3 Mbps and an upload rate of U. We have N peers in total.a. Assume U = 700Kbps. Calculate and compare the total amount of time needed to distribute the file for N = 5 and N = 50. How does increasing N affect this comparison ?b. Assume N = 50. Compare this time for U = 200 Kbps and U = 500 Kbps. How does increasing peer’s upload rate (U) affect this comparison?

# My question is related to computer networks and communication

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, by briefly justifying your answer:a. Why would a packet-switched network or a circuit-switched network be more appropriate for this application?b. Suppose that a packet-switched 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?
