Efficiently handle socket connection in C# RRS feed

  • Question

  • I currently have a scenario where more than ~10000 socket client trying to connect to my C# socket server which resides in cloud VM.

    I have written my socket server in the below way:

    var socketAccept = new TcpListener(IPAddress.Any, 1234);
    socketAccept.BeginAcceptTcpClient(OnAccept, socketAccept);
    private void OnAccept(IAsyncResult res)
        TcpListener listener = (TcpListener)res.AsyncState;
        TcpClient receiveSocket = listener.EndAcceptTcpClient(res);
        // Create a new thread which handles the specific socket for future requests (TCP read or write operation)
        listener.BeginAcceptTcpClient(OnAccept, listener);

    And this approach is not capable of handling ~1000 socket connection concurrently.

    Is there any efficient approach to handle this scenario?

    Thanks, Gowtham

  • Hi Gowtham,

    For async operation, you may consider Task instead of BeginAcceptTcpClient. But, you may consider whether you have such computer resource to open so many connections.

    I think you could set up multiple TCP Server to receive client sockets and then use Load Balancing to router the Socket requests.
