I'm coming from Java and there we use the EPoll selector implementation that comes with the JDK for non-blocking / asynchronous networking TCP and UDP development. Therefore you don't have to make choices.

But when it comes to C++ there are dozens of options to choose from according to this answer: https://stackoverflow.com/questions/118945/best-c-c-network-library

I don't have experience with C++ so I don't know. Which one should I pick for low-latency, asynchronous, non-blocking, real-time, selector style network programming? Does C++ even have a standard non-blocking network library or are they all external / independent?

networking will be available as standard only in c++17, currently boost is an option if you want to abstract the operational system features ( epool, kqueue, io completion ), low latency or realtime try dpdk to bypass operational system kernel.

  • $\begingroup$ Thanks! But c++17 is coming only in 2017 the earliest, right? Can you explain the difference between Boost.Asio and Asio? $\endgroup$

  • $\begingroup$ its the same thing, they explain here think-async IMO the main difference is the possibility to use the library without need of boost, some developers doesnt like it :D $\endgroup$

Take a look on POCO. This is really good library.

Another link I consider you should to check is ACE. You may find it a bit outdated and hard to understand from first try but concept is very close to MINA and NIO.
