I'm building an Objective-C app that has both a server and a client. The client can send updates to the server, and the server needs to be able to send updates to each connected client. I've been thinking about how best to implement this system, but am asking for your suggestions.
Currently, I'm thinking that when new updates are available, the server will use threads to send the update to each client in turn. If a client times out, they are disconnected. I have very little networking experience, so am asking your insight.
Do you think that this system would work well? If so, do you have any suggestions about how to do the threading? Any NS classes you can point me at? There's got to be some kind of queue I can use, I'm thinking.
Any other thoughts?
EDIT: I do not expect the client count to get much above 50 or so, at the max.
