> Hello Chris, > > How complex does our UDP packet-loss detection have to be? For example, messages might get split, so we could add packet-joining capability. However, most of the messages exchanged between stations are less than 1000 bytes, so it seems unlikely that messages will need to be split and joined. There's lots of things that we could do to correct packet loss, or to make the protocol more efficient, but I don't want to make it too simple or too complex. What should be the goal for full marks? Is a simple stop-and-wait protocol sufficient?
