2. Textbook problem 10 (35 points)

P10. Consider a short, 10-meter link, over which a sender can transmit at a rate

of 150 bits/sec in both directions. Suppose that packets containing data

are 100,000 bits long, and packets containing only control (e.g., ACK or

handshaking) are 200 bits long. Assume that N parallel connections each

get 1/N of the link bandwidth. Now consider the HTTP protocol, and suppose

that each downloaded object is 100 Kbits long, and that the initial downloaded

object contains 10 referenced objects from the same sender. Would parallel

downloads via parallel instances of non-persistent HTTP make sense in this

case? Now consider persistent HTTP. Do you expect significant gains over

the non-persistent case? Justify and explain your answer.
