Abstract:

To meet the isolation requirements of power enterprise networks,a security management system including the network core,aggregation layer and the access layer is built based on the principles of MPLS VPN and the reality of Chuzhou power system networks.The basic principles of the MPLS VPN technology are introduced.Practical applications show that the MPLS VPN not only can divide the existing network into logically isolated networks for the separation of different business systems,but also combine the advantages of the outer network and inner network to provide the users with high-quality network services.

Key words: MPLS VPN;WAN;business separation
