Turning packet chaos into orderly communication, one acknowledgment at a time.

MTP (Modified Transport Protocol) is a custom implementation of a reliable transport protocol built on top of UDP. This project demonstrates the principles of network protocols, concurrency, and error handling in networked systems.

Complete Documentation is present at doc

• Reliable data transfer over unreliable UDP
• Sliding window flow control
• Multi-threaded architecture for concurrent operations
• Shared memory IPC supporting up to 25 simultaneous MTP sockets
• Simulated unreliable network conditions for robustness testing

• msocket.h and msocket.c: Core MTP implementation
• initmsocket.c: Initializes MTP sockets, starts threads and garbage collector
• user1.c and user2.c: Example applications using MTP sockets
• Makefile: For compiling the project

1. Clone the repository:

   git clone https://github.com/lurkingryuu/mtp_socket.git
   cd mtp-protocol
   

2. Compile the project:

   make
   

1. Start the MTP initialization process:

   make runinit
   

2. In separate terminals, run the sender and receiver:

   ./sender -p 8080 -h 127.0.0.1 -P 9090 -H 127.0.0.1 -f sample_100kB.txt
   ./receiver -p 9090 -h 127.0.0.1 -P 8080 -H 127.0.0.1 -f received.txt
   

Run multiple sender-receiver pairs:

./sender -p 8080 -h 127.0.0.1 -P 9090 -H 127.0.0.1 -f sample_100kB.txt
./receiver -p 9090 -h 127.0.0.1 -P 8080 -H 127.0.0.1 -f received.txt
./sender -p 8081 -h 127.0.0.1 -P 9091 -H 127.0.0.1 -f sample_100kB.txt
./receiver -p 9091 -h 127.0.0.1 -P 8081 -H 127.0.0.1 -f received2.txt
