Netty是一个高性能、异步事件驱动的NIO框架，它提供了对TCP、UDP和文件传输的支持，作为一个异步NIO框架，Netty的所有IO操作都是异步非阻塞的，通过Future-Listener机制，用户可以方便的主动获取或者通过通知机制获得IO操作结果。

作为当前最流行的NIO框架，Netty在互联网领域、大数据分布式计算领域、游戏行业、通信行业等获得了广泛的应用，一些业界著名的开源组件也基于Netty的NIO框架构建。(Netty is a high-performance, asynchronous event driven NIO fr a mework that provides support for TCP, UDP and file transmission. As an asynchronous NIO fr a mework, all IO operations of Netty are asynchronous and non blocking. Through Future-Listener mechanism, users can easily obtain or obtain IO operation results by notification mechanism.



As the most popular NIO fr a mework, Netty has been widely used in the field of Internet, large data distributed computing, game industry, communication industry and so on. Some well-known open source components in the industry are also based on the NIO fr a mework of Netty.)
