Socket programming in c. Transferring large files over TCP, implementing Realiable UDP and simulating Packet Loss. As an assignment in Computer Networking @ Ariel University

Socket Programming Project in C

- Implementing a simple Reliable UDP (RUDP)

• Designing packets (header and data)
• Splitting large data into chunks
• Adding reliability with a handshake to start connection, ACK packets, and checksum
• Optimizing performance with high packet loss by adjusting timeout delays and max retries to resend packet
• Simple API

- Transferring large files over TCP or RUDP

- Simulating packet loss in order to:

• Compare TCP Reno and TCP Cubic
• Compare TCP and RUDP

Example runs:

Part A - Tranferring a large file over TCP:

Choosing between TCP Reno and TCP Cubic
