yojimbo VS Boost.Asio

yojimbo/ netcode/ reliable, all developped by Glenn Fidler, author of GafferOnGames

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

Indeed looks like it, strand_executor_service.hpp is using a Mutex internally (otherwise it wouldn't make sense to me).

as a side note, Asio is also released as an independent library without the boost stuff https://think-async.com/Asio/

Now that vinniefalco is going to kill off the asio standalone (see deprecate standalone ) and only support boost what would people then recommend to switch over to.

The ASIO framework can be found at https://think-async.com/Asio/ and the relevant license for its use is included in the GitHub repository in the Vendor/licenses directory.

The library is found at https://think-async.com/Asio/.

Asio Extracted from the much bigger Boost C++ library, it's apparently a really good networking library. As a bonus it also handles async / threads. Here's a really good video tutorial by OneLoneCoder

Yes: https://github.com/chriskohlhoff/asio/blob/master/asio/include/asio/coroutine.hpp

Here's the main contributor to Asio. I looked at Asio's repository and this was the first guy.
