The authors design a security model based on this protocol to conduct network management. The principle of this model is to use the extended features of EAP to force users to update the OS and the virus feature library. Using this model to implement network management can reduce objective threats of end users， reduce spam traffic， increase the payload of the network， and enhance the security of the network. 　　Key words：Multi-authentication； DIAMETER； EAP； Network admittance 　　Xie， X.

The main reason is in the process of informatization， although safety education is enhanced， some safety precautions are not implemented due to a shortage of personnel and low professional quality. 　　In the mobile Internet era， big data services become inevitable， and information security becomes increasingly important. Services to prevent illegal access， services of system version management， and virus defense have become important work for network management. 　　1.
