TDM(Time Division Multiplex)

Below is a basic example of a Time Division Multiplexing (TDM) system implemented in C# using sockets for communication. This example demonstrates how to implement a simple server-client architecture where the server multiplexes multiple client connections over time.

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;

public class TdmServer
{
    private TcpListener listener;
    private bool isRunning;

    public TdmServer(int port)
    {
        listener = new TcpListener(IPAddress.Any, port);
    }

    public void Start()
    {
        isRunning = true;
        listener.Start();
        Console.WriteLine("TDM server started.");

        while (isRunning)
        {
            // Accept client connection
            TcpClient client = listener.AcceptTcpClient();
            Console.WriteLine("Client connected.");

            // Handle client communication on a separate thread
            Thread clientThread = new Thread(() => HandleClient(client));
            clientThread.Start();
        }
    }

    private void HandleClient(TcpClient client)
    {
        NetworkStream stream = client.GetStream();
        byte[] buffer = new byte[1024];
        int bytesRead;

        // Simulate TDM multiplexing by sending data in fixed intervals
        while (true)
        {
            string data = "Sample data from server."; // Data to be sent to clients

            // Send data to client
            buffer = Encoding.UTF8.GetBytes(data);
            stream.Write(buffer, 0, buffer.Length);

            // Wait for a fixed interval (e.g., 1 second)
            Thread.Sleep(1000);
        }
    }

    public void Stop()
    {
        isRunning = false;
        listener.Stop();
        Console.WriteLine("TDM server stopped.");
    }
}

class Program
{
    static void Main(string[] args)
    {
        int port = 1234; // Port number for server
        TdmServer server = new TdmServer(port);
        server.Start();

        Console.WriteLine("Press Enter to stop the server.");
        Console.ReadLine();

        server.Stop();
    }
}
