Based On MPLS/VPN Of Jinhua Telecom DCN Network Reconstruct

This study, which is the author sufficiently researched the principle, mechanism and application method of MPLS and MPLS/VPN, according to the DCN network of Jinhua Telecom and the project requirement of Zhejiang Telecom, in 2004, designed and realized the reconstruction of Jinhua Telecom DCN network.The DCN network of Jinhua Telecom, as an integrated supporting network of its inner business, office work, network management and environment supervision, etc., must be strong, safe, reliable and controllable. With MPLS and MPLS VPN technology, we could build a reliable, agility and safe DCN network.In this study, the author resolved the MPLS arrangement, MPLS VPN construction and the programming & setting of each VPN RD/RT of DCN network. With RT and Option B method, we realized the communication of different VPN and link the Jinhua DCN network to Zhejiang Telecom network. The traffic flow is guided according to specific equipment configuration and difference. The unite export is founded under MPLS VPN through MP-IBGP. The author also brought out the opinion of different nodes access method to VPN and explored six MPLS VPN business models according to founded MPLS network.Until now, the Jinhua DCN network based on MPLS & MPLS VPN runs safe and sound. The network is also easy to be extended. These days, 114 private network has been conveniently accessed.
