ShuffleRouter

Build status shufflerouter

A testbed for the practicals of the Redes de Ordenadores subject

Overview

This is a simple echo server that redirects received UDP packets after a random amount of time —so packets can get reordered or even dropped—.

Received packets must carry the destination address in the first four bytes of the payload and the destination port as the fifth and sixth byte. All of them in network byte order. Packets are forwarded with the first six bytes replaced by the sender's IP address and port.
