Calculate round trip latency using C# in Console Application

Calculate round trip latency in C# console application

Write a program using sockets to send a 1-byte message from a client to a server and then have the server return the message to the client.

This process should be repeated in a loop for 1000 iterations and the average round trip latency should be calculated.

Follow the same procedure as above for messages of size 1 KB, 2 KB, 4KB, 8KB, and 16 KB.

Determine the effective through put for each message size.
