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?

I suggest that you keep thinking or designing your protocol - I can't imagine any protocol requiring any UDP message between station-servers to be bigger than a few hundred bytes (given that we've defined the maximum station name size to be 60 bytes). Perform a Google search for 'maximum UDP payload', and re-read what UDP provides in terms of delivery correctness. For the project, we're looking for correctness first, with the need for any efficiency almost non-existent.
