Hail all!

In spite of the fact that I'm still re-doing the Feature Analysis, there's nothing wrong with getting prepared for the design and/or implementation. The first system we'll be implementing is the networking system. The reason for this should be apparent. Ya' can't make a multi-player game without networking, and the synchronization between the client & server is such an integral part of the architecture that it makes little sense to attempt to add networking after-the-fact.

As a result, I've added the first research topic. Listed below are the .NET namespaces we may be using, the website for a freely available C# UDP wrapper library, other websites with networking information, and finally...for the more masochistic, the RFC's for TCP and UDP that are most well known.

If you know of any valuable networking resources which may help myself, or others with completing the networking component of this project, feel free to add a comment to this post.

So with no further ado, here's the first research topic info.

Available Network Libraries

A well known C# Socket library called: Lidgren

Hi,

There is another C# library for networking.

It is RUDP

www.codeplex.com/RUDP

It is more powerful than "lidgren". It is currently in beta but soon will use the same congestion protocol than CTCP (New Vista TCP Stack).

Also, there are some new features like :
- MTU Discovery (On some network without this lidgren will never be able to communicate)
- NAT Traversal

....
