After reading a bit more about how Gnutella and other P2P networks function, I wanted to start my own peer-to-peer system. I went in thinking that I would find plenty of tutorials and language-agnostic guidelines which could be applied, however I was met with a vague simplistic overview.
I could only find very small, precise P2P code which didn’t do much more than use client/server architecture on all users, which wasn’t really what I was looking for. I wanted something like Gnutella, but there doesn’t seem to be any articles out in the open for joining the network.
I had to write a basic Gnutella client in C# using Web Services and I think the class notes on the P2P stuff are still available here and here.
