Project description: The TCP/IP stack has five layers, namely application, transport, network, link, and physical. In Phase 1 of the project, each student has to implement the standard user datagram protocol (UDP) sockets. The intention is to transfer a file (use an image file) between a UDP client process and a UDP server process. Note that the client and server process can reside on the same host, but have to use different port numbers. Make sure that your program can transfer files (or data) in both directions.
