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.
