Transmission Control Protocol Lite
Completion: March 2022
LOGIC:
This program follows the structure and logic as presented in the TCP Lite assignment, implementing a simiplified version of TCP on top of UDP.
Transfer Process:
Upon loading up the server receiver and the client sender, the client sends a SYN segment to the server, in which case the server responds to the client with a SYN ACK, and the client finishes this handshake with an ACK.
After this handshake, the client is able to send over its data in segments of size 1024, which are taken in and appened to a file by the server.
Finally, after an EOF is read from the client's file to be sent, the client sends a FIN segment to initiate a closed connection. The server responds with a FIN ACK, and the client sends an ACK before closing its TCP connection. The server persists its connection as well, as it is a server.
TOOLS:
Wireshark was used along RFC 793 to find out how to construct the TCP headers, and the protocol that is used to send data over TCP.
