Which socket-based model should be used for many simultaneous connections?

Question

I need to know which socket-based model is best for servers with many simultaneous connections, just like on an MMORPG server.

I read about c10k, but what should I use if, for example, my server allows only 5,000 clients at a time? Blocking sockets, streaming (one thread per client)? Non-locking connectors, without thread? loop processing all clients in only a few threads? IOCP?

What are the advantages and disadvantages in short? I am already googled, but I have not found a specific cons article about all of these models.

Or is there an easier way to deal with the c10k problem?

Platform: Windows XP

Answer 1

Personally, I suggest you use an IOCP-based design, but then I would say that since I have an IOCP-based infrastructure , I have used high-performance servers for clients for many years.

I recently put together some of my reasons for preferring IOCP to other models available in windows, and they are available here on my blog here .

I / O ports cost almost nothing, and this also applies to multiple threads. Therefore, if you can quickly execute your bits, there really is no limit to the number of I / O operations that the NT engine can handle. Your internet connection is likely to be saturated.
