A link simulator for the first networking project (LINGI1341)

This program will proxy UDP traffic (datagrams of max 528 bytes), between two hosts, simulating the behavior of a lossy link.

Using it is a simple as choosing two UDP ports, one for the proxy, and one for the receiver of the protocol.

Client machine:

./sender server_address proxy_port

Server machine:

./link_sim -p proxy_port -P server_port &
./receiver :: server_port

You can control the direction (i.e. forward, reverse or both ways) of the traffic which is affected by the program.

Use this to test your programs in the events of losses, delays, truncation, ...
