ReliaNet: TCP-Like Reliable Data Transfer

ReliaNet is a project that demonstrates the implementation of a reliable data transfer protocol similar to TCP, ensuring successful communication over an unreliable connection with packet loss and latency.

Files

• reliable_transfer.py: The main file containing the implementation of the send and recv functions for the reliable data transfer protocol.
• tester.py: A script used to test the reliable_transfer.py under different conditions, such as varying packet loss rates and latencies.
• sender.py: A script simulating the sender side of the communication, which uses the send function from reliable_transfer.py to transmit data over the unreliable link.
• receiver.py: A script simulating the receiver side of the communication, which uses the recv function from reliable_transfer.py to receive and reconstruct the transmitted data.
• server.py: A script simulating the unreliable link between the sender and receiver, introducing packet loss and latency based on the parameters set in the tester.py script.

`testing the implementation

1. Test your file using the tester.py script. For example:

python3 tester.py --file test_data.txt --loss 0.05 --delay 0.1

This command tests the reliable_transfer.py sending the test_data.txt file over an unreliable connection with a 5% packet loss rate and a 100ms delay.

You can replace 'test_data.txt' with any other file you would like to send and test.

2. You can view the available options and parameters for the tester.py script by running:

python3 tester.py --help

This will display a help message with information on the optional arguments and their usage.

Requirements

• Python 3

Ensure that Python 3 is installed on your system to run the project.
