server.c and client.c - implementation of go-back-n ARQ in C by Elijah Jordan Montgomery <[email protected]> Server.c implements a reliable data transfer over UDP in C client.c implements a reliable data transfer client over UDP in C Both of these programs use the go-back-n ARQ, that is lost data is automatically resent. These programs are hardcoded to transfer 8192 bytes of data in any chunksize from 1 to 512 bytes per packet to compile: gcc -o server server.c gcc -o client client.c to run: first run the server. Usage is: "./server <PORT> <CHUNKSIZE> [<LOSS RATE>]" for example: "./server 1655 500 .50" will start a server on port 1655, with chunk size of 500 bytes and 50% loss rate. Loss Rate is an optional argument and does not have to be used Once the server is running, run the client. Usage is: "./client <SERVER IP> <SERVER PORT> <CHUNK SIZE> <WINDOW SIZE>" so for example: "./client 10.10.10.5 1234 500 3" will instruct the client to connect to the server at 10.10.10.5 on port 1234 and send 3 chunks at a time of 500 bytes.
