The current network software development has the problems of complex process, large network framework procedures, and large development costs. Based on the socket communication on the windows platform, this paper puts forward a lightweight high performance network communication component Isocket. It uses IOCP as the server-side, and EventSelect as the clientside, simplifying the original network framework. It designs the Agent component, providing interface service for the client and server. It designs the API interface based on Eventselect model, increasing the applicability of procedures integration, achieving a complete package of the communication of underlying network framework. It provides a new simplified method to increase the universality of software development and reduce the learning cost and development difficulty for developers.
