In this problem, we consider t

In this problem, we consider the delay introduced by the TCP slow-start phase. Consider a client and a Web server directly connected by one link of rate R. Suppose the client wants to retrieve an object whose size is exactly equal to 15 S, where S is the maximum segment size(MSS) Denote the round-trip time between client and server as RTT(assumed to be constant). Ignoring protocol headers, determine the time to retrieve the object(including TCP connection establishment) when
a. 4 S /R> SR +RTT> 2S/R
b. SR+ RTT> 4 SR
c. SR> RTT.
