KCP, a reliable ARQ protocol offering a TCP-like ordered stream over an unreliable datagram transport. Built shared as libkcp with an imposed soname, since upstream sets none. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

|
|
KCP is a fast and reliable ARQ protocol implementing a TCP-like reliable
|
|
ordered stream on top of an unreliable datagram transport such as UDP,
|
|
trading about 10-20% more bandwidth for 30-40% lower latency than TCP.
|
|
It is a pure algorithm: the caller supplies the datagram in- and output.
