  1. POHow to write a scalable Tcp/Ip based server
    text
    copied!<p>I am in the design phase of writing a new Windows Service application that accepts TCP/IP connections for long running connections (i.e. this is not like HTTP where there are many short connections, but rather a client connects and stays connected for hours or days or even weeks).</p> <p>I'm looking for ideas for the best way to design the network architecture. I'm going to need to start at least one thread for the service. I am considering using the Asynch API (BeginRecieve, etc..) since I don't know how many clients I will have connected at any given time (possibly hundreds). I definitely do not want to start a thread for each connection.</p> <p>Data will primarily flow out to the clients from my server, but there will be some commands sent from the clients on occasion. This is primarily a monitoring applicaiton in which my server sends status data periodically to the clients.</p> <p>Any suggestions on the best way to make this as scalable as possible? Basic workflow? Thanks.</p> <p>EDIT: To be clear, i'm looking for .net based solutions (C# if possible, but any .net language will work)</p> <p>BOUNTY NOTE: To be awarded the bounty, I expect more than a simple answer. I would need a working example of a solution, either as a pointer to something I could download or a short example in-line. And it must be .net and Windows based (any .net language is acceptable)</p> <p>EDIT: I want to thank everyone that gave good answers. Unfortunately, I could only accept one, and I chose to accept the more well known Begin/End method. Esac's solution may well be better, but it's still new enough that I don't know for sure how it will work out.</p> <p>I have upvoted all the answers I thought were good, I wish I could do more for you guys. Thanks again.</p>
