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 framework that provides support for TCP, UDP and file transmission. As an asynchronous NIO framework, 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 framework, 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 framework of Netty.)
