Question

Assume that you are downloading a set of HTTP objects across a 10 Mbps link.
Each object has 1000 bytes. The maximum segment size for the system is 1500 bytes.
What is the channel utilization (from the first SYN to the last ACK) if we are using:
a) Non-persistent connections
b) Persistent connections without pipelining
c) Persistent connections with pipelining
You can assume that the client supplies a %u201Cconnection: close%u201D header with the last HTTP
request, that there is a 15 ms propagation delay from one node to the other, that the
network does not lose or corrupt packets, and that the transmission time for an ACK and a
TCP header is negligible.
