C++11 library for network services on modern x86_64 Linux

libten Build Status

C++11 library for network services on modern x86-64 Linux.


  • lightweight cooperative tasks (using boost.context)
  • typed channels for communicating between threads and tasks
  • http client and server
  • fast uri parser
  • JSON parser (wrapper around jansson)
  • logging (glog)
  • rpc (using msgpack)
  • epoll event loop


Or rather why not libevent, libev, or boost.asio? libten is designed around the concept of task-based concurrency, while the other libraries are designed for event driven concurrency with callbacks. They are not entirely at odds, libten's event loop could be built on any of these libraries. However, another major difference is that other libraries strive to provide a cross platform solution to event driven network programming. They are great if you need portable code that works across many versions and platforms. libten's approach is to focus only on modern Linux, modern compilers, and performance. This makes libten's code base smaller and easier to maintain, with very minimal abstraction. libten uses epoll, timerfd, and signalfd. In addition to networking and concurrency it provides logging, JSON, URI, http client and server, rpc, zookeeper and more.

API Stability

libten is not a stable API yet. Don't let this scare you away though. Most changes at this point are minor and incremental.
