Research & Design Network Comunnication

[Indy2222]

Design:

• Internet games are started via a (central but configurable) lobby server (Lobby and Rendezvous Server #255). The server serves as a rendezvous.
• LAN games start the same server locally and announce it over mDNS.
• In came networking is based on a (custom?) peer-to-peer protocol.
  • This limits the load on the central server,
  • and decreases latency (especially on LAN and other close network endpoints).
• The over the Internet pear-to-peer connection is be established with Hole Punching technique.
• The (message oriented) communication is be based on UDP:
  • all messages are idempotent (thus packet duplication is not an issue) and order independent (thus reordering is not an issue),
  • most messages won't require 0% packet loss,
  • a to-be-decided technique is used to guarantee delivery of some messages.
