ENTS 640 Networks and Protocols I Project: Client-Server Application

This project focuses on designing and implementing a client-server application in Java using UDP sockets for data transfer. The client sends data packets containing two-dimensional vectors to the server, which performs computations and returns the result. A reliable data transfer protocol is implemented on top of UDP to ensure reliable communication between the client and server. The project details the packet structure, including the DATA packet format, and discusses key concepts such as client-server architecture, three-tier architecture, user datagram protocol (UDP), transmission control protocol (TCP), and socket programming. The implementation includes phases for data vector upload, computation request, and result download, along with the use of K-means clustering for data processing. Flow charts, block diagrams, UML class diagrams, and state transition diagrams are used to illustrate the system's design and operation. Output screenshots are also provided to demonstrate the application's functionality.
