netty

##1.Netty 簡介

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是一個NIO客戶端服務器框架，能夠快速輕鬆地開發網絡協議服務器和客戶端等應用程序。 它極大地簡化和精簡了
網絡編程，如TCP和UDP套接字服務器。
protocol：協議
development：發展，開發
simplifies： 簡化
streamline： 精簡



'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.

「快速簡便」並不意味着最終的應用程序會受到可維護性的影響或性能問題。Netty通過精心設計，具備豐富的協議，如FTP，
SMTP，HTTP以及各類二進制和基於文本的遺留協議所得到的最佳實踐

maintainability：可維護性 （n）
performance： 性能，表演 （Noun）
implementation：履行 （Noun）
various：各個 (Adjective)
legacy：遺產 (Noun)
flexibility：靈活性(Noun)
stability：穩定性(Noun)
compromise：妥協(Noun)
