# NOX/POX

[NOX](https://github.com/noxrepo/nox)是第一个SDN控制器，由Nicira开发，并于2008年开源发布。NOX在2010年以前得到广泛应用，不过由于其基于C++开发，开发成本较高，逐渐在控制器竞争中没落。所以后来其兄弟版本[POX](https://github.com/noxrepo/pox)面世。POX是完全基于Python的，适合SDN初学者。但POX也有其架构和性能的缺陷，逐渐也被新兴的控制器所取代。

目前，NOX/POX社区已不再活跃，其官网`http://www.noxrepo.org`也已废弃，不推荐在生产中继续使用它们。
