Abstract: Network component is a new distributed software component model and a hotspot research. This paper studies the structure of the network component, which consists of physics domain, individual domain and whole domain. The formalized definitions of the components are given, and whose basic characteristics are analyzed. To satisfy these characteristics, the system architecture for network component based on Web service is put forward. An application of the architecture system is given, which is composed of the network components.

Key words: network component, Web service, system architecture, distributed computing
