##1.Netty 简介
Netty is a NIO client server framework which enables quick and easy development of network
applications such as protocol servers and clients. It greatly simplifies and streamlines
network programming such as TCP and UDP socket server.
Netty是一个NIO客户端服务器框架，可以快速轻松地开发网络协议服务器和客户端等应用程序。 它极大地简化和精简了
网络编程，如TCP和UDP套接字服务器。
protocol：协议
development：发展，开发
simplifies： 简化
streamline： 精简
'Quick and easy' doesn't mean that a resulting application will suffer from a maintainability
or a performance issue. Netty has been designed carefully with the experiences earned from the
implementation of a lot of protocols such as FTP, SMTP, HTTP, and various binary and text-based
legacy protocols. As a result, Netty has succeeded to find a way to achieve ease of development,
performance, stability, and flexibility without a compromise.
“快速简便”并不意味着最终的应用程序会受到可维护性的影响或性能问题。Netty经过精心设计，具有丰富的协议，如FTP，
SMTP，HTTP以及各种二进制和基于文本的遗留协议所获得的最佳实践

performance： 性能，表演 （Noun）
implementation：履行 （Noun）
various：各个 (Adjective)
legacy：遗产 (Noun)
