And the improved methods of IOCP parameter extension , memory pool , object. pool .and ring- buffer were proposed respectively. On the basis of underlying encapsulation for IOCP using these methods , a scalable network communication module for enterprise applications was designëd and implemented. The experimental results show that the module can support massive concurrent connections , and has higher data throughput by reasonable resource consumption. The proposed solution has also showed good performance in the a
