CS4390-RDT-over-UDP

Summary:

This project aims to implement the Go Back N and Selective Repeat formulations of reliable data transfer over UDP.

Requirements:

This project runs on python 3.9+ and requires the following packages: configparser, socket, recordclass

How to run:

To run the tests, cd into ./validation-relay/ and run python3 validation-relay.py, this will run all tests by setting up a relay server which will emulate the delay and loss of a network. In order to run a specific test, comment out all non-relevant tests in the __main__ of validation-relay.py.
