A high-bandwidth and high-performance data communication network has been designed for the Sichuan power dispatch data network by using the IP over SDH technology based on the high reliability optical transmission channel.The data communication network can meet the requirements of data transmission needs from the Sichuan electric power operating and dispatching business.In this paper

the network topology

MPLS VPN

the strategy of the access layer

and the network management of the Sichuan electric power dispatching data communication network have been addressed in detail.Moreover

this paper provides recommendations for the further optimization to the backbone layer of the Sichuan power dispatch data network.
