Major networking enhancements to improve multiplayer performance and
reduce desync issues in games like Mario Kart 8 Deluxe:

Network Performance:

  • Add socket connection pooling in BSD service to reduce overhead
  • Implement unreliable packet delivery for latency-sensitive game data
  • Add packet reliability control for both ProxyPacket and LDNPacket
  • Use ENET_PACKET_FLAG_UNSEQUENCED for small UDP packets (<1200 bytes)

Monitoring & Debugging:

  • Add PacketStatistics struct to track sent/received/dropped packets
  • Enhanced logging for proxy packet handling and socket lifecycle
  • Periodic stats logging every 100 packets for diagnostics

Configuration:

Socket Management:

  • Implement SocketPoolKey for efficient socket reuse
  • Store domain/type/protocol info in FileDescriptor
  • Max pool size limit (8 sockets per type) to prevent memory bloat
  • Return closed sockets to pool when room is still connected

Protocol Updates:

  • Add 'reliable' field to ProxyPacket and LDNPacket structures
  • Update room.cpp packet handlers to respect reliability flags
  • Maintain backward compatibility with default reliable=true

These changes significantly reduce packet latency for real-time game
traffic while maintaining reliability for control packets.
