Consider a client connecting to a web server via a router as shown in Fig.Q2. Client A sends a request
to the server to retrieve a 7.5 Mbytes file. Given that the segment size is 50 Kbytes, the round trip
time (RTT) between the server and client is 10 ms, the initial slow-start threshold is 16 and the
client's buffer always has a storage space of 1 Mbytes. Assume that TCP Reno is used, there is no
loss during transmission and the headers of protocols are ignored.
