这是基于ACE开发的Reactor和Proactor模型的通讯库.在实践中已经使用。库本身支持文件的断点传输，并在实际中使用，希望给大家一个引子学习。-This is based on the ACE Reactor and Proactor model developed by the communication library has been used in practice. Breakpoint library itself supports file transfer, and in

从Java 1.7 以后NIO可以采用系统底层的Socket来实现了，大大提高了吞吐量。 相比Reactor方式，Nio2可以称为Proactor方式的实现。具体是程序避免等待而采用回调函数类。-From Java 1.7 after NIO Socket can be used to achieve the underlying system, and greatly improving the throughput. Compared to Reactor way, Nio2 may b
