a. Assume the application layer generates a message of size 2000 Kbits and that the segment size for the transport layer is 2000 bits. Would the message be broken into 2000 packets? Or would more or less be needed?
b. Can a client process open multiple TCP connections to the same server process? If so, how would the multiplexing and demultiplexing work properly?
c. We saw the FTP protocol uses out of band connections, in that the control and data are over separate TCP connections. Is it possible for an application to communicate out of band, where one band is TCP and the other UDP? If so, how would this be implemented? If not, explain why not. d. Imagine looking at the traffic intensity over time at a particular router in the network. Initially, the intensity averages 0.5, then after a period of time rises to 0.91 on average, then rises again to 1.39 and finally settles down around 0.27. Briefly explain what you would experience over these 4 phases of time.
