1. Aim: Designing and Implementation of a Reliable Protocol over UDP 2. Procedure: You will implement a reliable protocol using finite state machines on top of UDP. Your protocol should provide error checking and flow control. You will use Go-Back-N protocol for flow control. 2.1. High Level Design (HLD) of the system should provide state diagram of the sender and the receiver. 2.2. CRC will be used for error checking. CRC polynomial is 10101. 2.3. You will use a sliding window with 3-bit sequence numbers and a window size of 6. 2.4. Implementation can be done in Python, C, Java or Javascript in Linux/UNIX environment using UDP socket communication. 2.5. The message to be transferred will be 32 16-bit words of a text file.
