Reliable Data Transfer over UDP using sequential Stop-And-Wait ARQ (Automatic Repeat reQuest)
This repository provides interfaces rdt_send() and rdt_recv() that are developed on top of User Datagram Protocol using sequential stop-and-wait sequence and acknowledgement number based ARQs. A static timer is used for timeout-retransmission mechanism. To use these interfaces, include rdt.c and rdt.h and compile rdt.c along with your project. Port numbers can be tweaked from rdt.c.
While the performance is not better than TCP in the long run, it saves the connection establishment/termination and larger header overhead for small message sizes and should give a little performance boost. Some of the functions could have been optimal for which I chose readability over performance. For complete understanding, consider reading code comments and slides
