3.1 [Reference: pages 66, 105 in text] A client sends a 200 byte request message to a service, which produces
a response containing 5000 bytes. Estimate the total time to complete the request in each of the cases
below, with the performance assumptions listed as follows:
Latency per packet
(local or remote, incurred on both send and receive): 5 ms
Connection setup time (TCP only): 5 ms
Data transfer rate: 10 Mbps
MTU: 1000 bytes
Server request processing time: 2 ms
Assume that the network is lightly loaded.
i) Using connectionless (datagram) communication (for example, UDP)
ii) Using connection-oriented communication (for example, TCP);
iii) The server process is in the same machine as the client.
