BGP MPLS/VPN Technology In Province In The DCN Network Transformation The Design And The Realization

How does abstract this article mainly narrate in the Liaoning Province DCN net MPLS VPN to design and the realization. MPLS the VPN service is a new service, also is the present various operations business widespread use technology. Along with enterprise informationization advancement speeding up, various enterprises unit more and more are also many to own production special net use demand, simultaneously also to the network service way, the grade of service set a higher request. Along with the DCN network construction scale unceasing expansion, enterprise's production network with manages the public network to carry on the conformity also is ultimately. From the service development demand, the original network existence question is a starting point, through to several kind of network plan each aspect contrast, introduced MPLS VPN emphatically after the Liaoning Province DCN network the application theoretical analysis, the transformation the Liaoning Province DCN network design, Liaoning Province DCN net MPLS aspect and so on VPN design and realization contents.China Netcom Group Liaoning Province Subsidiary company makes something a matter of political "line" after the operation support system, the original DCN network cannot provide the enough band width and the stable movement environment, adds original backbone DCN to have aspect and so on network architecture, network equipment, management method, network security questions, in order to guarantee provides the network service to each kind of application, DCN must in aspects and so on network architecture, network band width, management method, safe guarantee make the corresponding transformation; In the provincial office entire province scope various network management system, the service operation support system, the new service using the platform, the business management information system and so on many kinds of application system construct the unification high speed, high grade, multi-service synthesis turning on and the data transfer platform.In the Liaoning Province DCN network process, we refer to several kind of mature network plans, passes through various aspects contrast,...
