M9Studio.UdpLikeTcp

Reliable UDP communication over unreliable networks with TCP-like delivery guarantees.

Features

• Reliable message delivery over UDP
• Packet fragmentation and reassembly
• ACK-based retransmission system
• Send and receive queues per endpoint
• NAT traversal ready (via STUN, optional)
• Simple API using IPEndPoint

Installation

dotnet add package M9Studio.UdpLikeTcp

Usage

Sending data

var socket = new M9Studio.UdpLikeTcp.Socket();
var target = new IPEndPoint(IPAddress.Loopback, 12345);
byte[] message = Encoding.UTF8.GetBytes("Hello over UDP!");
socket.SendTo(target, message);

Receiving data (blocking)

byte[] received = socket.ReceiveFrom(remoteEP);
Console.WriteLine("Received: " + Encoding.UTF8.GetString(received));

Using the event system

socket.DataReceived += (sender) =>
{
    byte[] buffer = socket.ReceiveFrom(sender);
    Console.WriteLine($"Received {buffer.Length} bytes from {sender}");
};

socket.Connected += (sender) =>
{
    Console.WriteLine($"{sender} is connected");
};

Notes

• Supports .NET 8.0+
• Cross-platform: Windows, Linux, macOS
• STUN and public IP detection supported externally
