Under the WAN environment,large-scale VPN networks is effectively and safely managed by long-distance centralized mana-gement system based on SNMP.To solve the flaw of topology discovery,a method in which agent initiates registry to the server is pro-posed.After analysis of the SNMPv3 security features,the public key authentication mechanism is introduced and the procedure of key negotiation is discussed in detail.For poor reliability and real-time data transmission of UDP-based SNMP,a strategy of configuration based on XML is given,which is proved to be feasible and efficient by the result of experiment at last.
