This paper first discusses the disadvantages of existing network information auditing systems with single host architecture.Then gives out a new auditing system architecture,which has a shared port for the total information and processes two-level information flow.The whole system is composed of local sub-systems and a global communicating and authenticating agent. Inside each sub-system,slow modules and fast modules are implemented in a distributed pattern to improve the efficiency and flexibility of the whole system.Intercommunicating regulations between the global communicating and authenticating agent and the local sub-system is discussed simply in the last section of this paper.
