Actualization of metropolitan area network construction and end to end VPN in Guangzhou electric power

ZHANG Bin~(1),CHEN Jun~(2)(1.Guangdong Electric Power Design Institute,Guangzhou 510640,China;2.Guangzhou Power Supply Bureau,Guangzhou 50620,China)  
With the development of power system informationization,the demand on communication bandwidth,such as OA,financial MIS,marketing MIS,is becoming higher and higher.To meet the development demand,the Metropolitan Area Network(MAN) construction was divided into two phases in Guangzhou Power Supply Bureau.The MAN bears various businesses and lays over all nodes of subsidiary units and the power supply stations in city zone.The paper introduces the network mode and relevant technologies used in this two phases.The technical continuity and compatibility used in the two phases are analyzed emphatically,and according to the actual condition,how to extend the backbone network to the nodes in satellite town are mentioned especially in the paper also.With the using of MPLS,Multi-VRF and end-to-end VPN business access technologies,different information businesses are isolated;the security of information system is strengthened;and makes great strides in the enterprise informationization construction.
