golang-github-xtaci-kcp-dev - 5.6.1-2 main

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.
