The purpose of this paper is to set up an efficient and secure data transmission channel to transfer the security data between the management platform and the distributed security agents on the internet. We analyses the basic principle and characteristic of the data security transfer and multi-protocol communication model in the distributed management network base on new network management and security data transfer technology, and proposed the actual system structure of this model. Furthermore, this model carries on a lot instructive test and get well along with opening interface, real-time management, expansibility, human interface and crossing flat ability, which guarantee the successful application of a distributed network management system. Moreover, the system applies itself successfully to campus network testing.
