Data Link Layer Code for Implementing a Simple Reliable Data | Instant Homework Help

In this programming project, you will be writing sending and receiving data link layer code for implementing a simple reliable data transfer protocol. There are two versions of this project, the stop and wait for version and the GBN version.This project prototypes are protocol3 and protocol5 in chapter 3 the data link layer of the textbook. You should implement the function from_physical_layer() and to_physical_layer() using UDP socket API. You should also implement other functions to make protocol3 and protocol5 runnable. Sender must display variable next_frame_to_send, ack_expected, s.seq. Receiver must display variable frame_expected. Sender will send 9 frames every 10 frames to simulate frame lose.You must submit the following files:The project design document: for example, flow chart and running screen display.Source code and executable file
