Server

SP2P (Super Peer-to-Peer) Relay Server

Responsibilities:

• Accepts TCP connections from clients.
• Assigns unique 8-character hex addresses to clients.
• Allows clients to connect to each other via the CONN <ADDRESS> command.
• Relays data between paired clients.

SP2P Protocol:

• On connect: YOURADDR <ADDRESS> is sent to the client.
• To connect to a peer: send CONN <TARGET_ADDRESS>.
• On success: connecting client receives OK, the target peer receives CONNED <ADDRESS>.
• All relayed messages: <SENDER_ADDRESS>: <DATA>.
• On disconnect initiated by a peer: the other side receives DISCONN.

Client

SP2P (Super Peer-to-Peer) TCP Client

Responsibilities:

• Connects to an SP2P Server and receives its unique address.
• Sends CONN <ADDRESS> to initiate a connection to another peer.
• Handles incoming commands and packets:
  • YOURADDR <ADDR>: own assigned address
  • OK: connection to peer successful
  • CONNED <ADDR>: peer has connected to you
  • DISCONN: peer has disconnected
  • <ADDR>: <DATA>: message relayed from peer

Hooks (override in subclass or override instance methods):

• on_ready(address): Called with own address after connecting to server.
• on_connected(): Called after successful connection to peer.
• on_peer_connected(peer_address): Called when a peer connects to you.
• on_disconnected(): Called when the peer disconnects.
• on_message(sender_address, message): Called on incoming message.
