Research and implementation of an intelligent traffic monitoring system based on IOCP mechanism

According to the function of intelligent traffic monitoring system and the problem that the load of the intelligent traffic server is big, the principle, programming methods and technical difficulties of IOCP(I/O Completion Port) mechanism in Windows used in network communication program are analyzed. The design method of cooperating multi-threads and simplifying the function of the single thread is brought forward. And this is applicated in designing the server of the intelligent traffic monitoring system. The performance of the server based on the IOCP mechanism is compared with the performance of the server based on the overlapped I/O mechanism. It is showed from the test that IOCP mechanism has good technical advantages in the process of the design of large-scale network communication system.
