Full-Featured Reliable-UDP Library for golang

KCP (golang-github-xtaci-kcp-dev) is a Production-Grade Reliable-UDP library for golang. It provides fast, ordered, and error-checked delivery of stream over UDP packets.

It has been well tested with opensource project kcptun, which runs on millions of devices, from low-end MIPS routers to high-end servers. It also runs well for applications like online games, live broadcasting, file synchronization and network acceleration.

Features:

  * Optimized for Realtime Multiplayer Games, Audio/Video Streaming.
  * Compatible with skywind3000's (https://github.com/skywind3000)
    C version with optimizations.
  * Cache friendly and Memory optimized design in golang.
  * Compatible with net.Conn (https://golang.org/pkg/net/#Conn)
    and net.Listener (https://golang.org/pkg/net/#Listener).
  * FEC (Forward Error Correction)
    (https://en.wikipedia.org/wiki/Forward_error_correction)
    Support with Reed-Solomon Codes
    (https://en.wikipedia.org/wiki/Reed%E2%80%93Solomon_error_correction)
  * Packet level encryption support with AES, TEA, 3DES, Blowfish, Cast5,
    Salsa20, etc., in CFB mode.
  * O(1) goroutines created for the entire server application, minimized
    goroutine context switch.

Conventions:

  Control messages like SYN/FIN/RST in TCP are not defined in KCP.
  You need some keepalive/heartbeat mechanims in the application-level.
  A real world example is to use some multiplexing protocol over session,
  such as smux (golang-github-xtaci-smux-dev) with embedded keepalive
  mechanism. See kcptun (https://github.com/xtaci/kcptun) for example.
