A process A wants to send a dataset of 3 MB to a process B using a message passing mechanism. Estimate the total time required to complete the transfer in each of the following cases, with the performance assumptions listed below:

a. Using connectionless (datagram) communication (for example, UDP);

b. Using connection-oriented communication (TCP);

c. When the two processes are on the same machine.

Latency per packet (remote, incurred on both send and receive): 5 ms

Latency per packet (local, incurred on both send and receive): 2 ms

Connection setup time (TCP only): 5 ms

Data transfer rate: 10 Mbps

Maximum transfer unit (max packet length): 1000 bytes
