ChaseNet2

Peer to peer networking library written in pure C#

Advantages

• Real P2P system
• Powerful serialization system
• Custom protocol
  • Low latency - UDP based
  • Message acknowledgement and retransmission
  • Message compression
  • E2E encryption

Basic Usage

Most important classes are ConnectionManager and Connection. ConnectionManager is used to create connections and listen for incoming connections. Connection is a point to point connection between two ConnectionManagers.

// Create a connection manager
var connectionManager = new ConnectionManager(); // optionally pass a port number to listen on
connectionManager.StartBackgroundThread(); // start a background thread to handle network events

// Create a connection to another connection manager
var connection = await connectionManager.CreateConnection(IPEndPoint.Parse("127.0.0.1:1234"));

// Register the message class with the serialization system (Any class that can be serialized with Protobuf-net)
connectionManager.Serializer.RegisterType<string>();

// Send a message
// (message type, channel ID, message content)
var sentMessage = connection.EnqueueMessage(MessageType.Reliable | MessageType.Priority, 1234, "Hello !");

// Receive a message
connection.IncomingMessages.TryDequeue(out var message)
switch (message.Content)
{
    case string str:
        Console.WriteLine($"Received string: {str}");
        break;
}
