Consider a chain topology with four hosts and as shown below:
ABCD
Host serves as the client and host serves as the server. The four
hosts have the same buffer size.
The link has a rate kbps the link has a rate kbps and the link has a rate kbps Hosts and are separated by meters, hosts and are separated by meters, and hosts and are separated by meters. The propagation speed along each link is times meterssec Suppose, host sends a packet of bits to host
i Ignoring processing and queuing delays, find the endtoend delay
ii Suppose, network congestion occurs. Which link is likely to become the bottleneck? Explain your answers.
iii Suppose, the packet that host sent reaches host Upon receiving the packet, host sends another packet back to host What is the response time for the packet at host
iv Suppose, a web cache is installed at client host and the miss rate is Find the total response time.
