Abstract: This paper analyzed a single client一mufti-server model based on specific network applications. This paper not only gave the client basic implementation based on IOCP, but also gave the thread scheduling, asynchronous connections IOCP framework method. Aiming at receiving variable length data for the reduest,memory pool management and buffer settings were analyzed and designed. By connecting test and throughput test, results show that this design has capabilities of a large number of connections and efficient data processing. The recommendations of the number setting of IOCP worker threads were given by the experimental methods.
