hey all, I am tryig to design a network engine. basicly it is a wrapper which will be like a Directplay. I would really like to know some design ideas because I am a bit lost in the huge possibilities. If someone has already worked on something like this and might provide me an example of his work or guide me. thank you.

well, i don't wana use a library.
I am using plain sockets the engine will be crossplatform and the company wants it to be built from scratch. what i would like is a small design or idea if possible.
for now i have a class that manages sessions , were u can create or join a session or view remote sessions.
thenthe session class which manages the players and player groups and the communication between them. and there is a callback function here ran every game loop.
you see the engine will have to be a bit general (like directplay only crossplatform). and will be used in a new Game Engine so it isn't specific for a game or so.
