Develop a TCP-based client-server socket program for transferring a large message. The message transmitted from the client to server is read from a large file (size is about 30000 bytes). The entire message is sent by the client as a single data-unit. After receiving the file, the server sends an ACK message to the receiver. Verify that the file has been sent completely and correctly by comparing the received file with the original file ("diff" command could be used). Measure the message transfer time and throughput.
