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 > S/R + RTT > 2S/R
b. S/R + RTT > 4 S/R
c. S/R > RTT.
Consider the following data:
The transmission rate of Client and Web = R.
Maximum Segment Size (MSS) = S
Round Trip Time (RTT) between client and server is constant.
