Object-oriented networking

Question

I\'ve written a number of networking systems and have a good idea of how networking works. However I always end up having a packet receive function which is a giant switch stat

Answer 1

About the way to handle the packet type: for me the map is the best. However I'd use a plain array (or a vector) instead of a map. It would make access time constant if you enumerate your packet types sequentially from 0.

As to the class structure. There are libraries that already do this job: Available Game network protocol definition languages and code generation. E.g. Google's Protocol Buffer seems to be promising. It generates a storage class with getters, setters, serialization and deserialization routines for every message in the protocol description. The protocol description language looks more or less rich.
