Kcptun is a very simple and fast UDP tunnel based on the KCP protocol. It can convert TCP flows to KCP + UDP streams and can be used for transmission of any TCP network program to improve network fluency in packet loss environments.

KCP is a fast and reliable protocol that can reduce the average delay by 30% to 40% and triple the maximum delay by a factor of 10% to 20% less than TCP’s waste.

Kcptun v20171021 version of the new ‘-quiet’ option, can be used to curb the meaningless “stream open/close” message.
