Question

Suppose a client wants to get a page consisting of 5 objects from a web server.

Each object (including the base html file) is 100,000 bits and the total service rate of server is 5Mbps.

The RTT between the web server and the client is 100 msec.

How much time does it take for a the client to receive all 5 objects using:

(a) Nonpersistent HTTP

(b) Persistent HTTP without pipelining? (1pts)

(c) Persistent HTTP with pipelining? (1pts)

Now if the service rate “per object” is limited to 1Mbps, revise your answers to (a), (b), (c).

Explanation / Answer

a) RTT1 + * + RTTn + 2 RTTo + 8 2 RTTo = 18RTTo + RTT1 + * + RTTn

b) RTT1 + * + RTTn + 2 RTTo + 2 2 RTTo = 6 RTTo + RTT1 + * + RTTn

c) RTT1 + * + RTTn + 2 RTTo + RTTo = 3RTTo + RTT1 + * + RTTn
