KCP VS yojimbo

KCP Is a kind of protocol ( like UDP and TCP ) that is reliable like TCP but is faster, at to cost of slightly bigger bandwidth costs.

I'd consider KCP protocol over TCP, it has 30-40% lower latency at the expense of 20% higher bandwidth.

i see, i know KCP implementation i don't see in your code any of the GO KCP implementations did you write it by yourself?

They really just didn't know how to go about building a complex online game or what that entails. At one point they were trying to donate to open source networking projects that were still in development and not production-ready in hopes they'd help them make their game, you'll see them listed as sponsors of yojimbo for example. It was bizarre to watch.

I can't remember exactly how best to handle this (Glenn's yojimbo project is probably your best bet for a concrete implementation), but here's an idea: buffer and ACK some packets (e.g. up to N packets following your missing packet) and discard everything else (without ACK) until the missing one shows up. The protocol will then continuously try to send your missing packet, in addition to the packets you've intentionally not ACK'd. Once the missing packet shows up you can process it and any buffered packets up to your next missing packet and repeat.

You may want to take a look at yojimbo , looks like it will fit your requirements pretty well.

And has his own C++ library for transmitting messages over UDP protocol https://github.com/networkprotocol/yojimbo
