基於事件驅動、使用NIO的Netty2庫

Netty 2 provides an easy event-based API (like Swing) to develop high-performance, maintainable TCP/IP server/client application. Netty provides many essential features such as readiness selection, thread pooling, write buffer DoS prevention, and buffer reuse which are required to build high- performance and capacity network applications.
