Research On Plan And Arrangement Of MPLS VPN In The Shandong Unicom DCN Network

The Data Communication Network of Shandong Unicom is a special data communication network, which carries the business support system, the operation support system, the managerment support system and other system to support the daily operation of the company. With the limitation of technology and equipment in the early construction of DCN, the access control list (ACL) is used to divide the 3-layer routes among various dedicated computer networks in DCN. Because the network scale is expanding and complexity is increasing. With the addition of new business and the extension of existing business, the network can not meet the need of growing business enterprises. In order to change this situation and meet the need of enterprises, the present network of DCN must be reconstructed.Virtual Private Network (VPN) based on Multiprotocol Label Switching (mpls) technology can resolve the problem of logically separate amd divide dedicated computer networks in DCN. With MPLS and MPLS vpn technology, we could build a reliable, agility and safe DCN network.In this thesis, the author analyses the advantage of using MPLS VPN technique, analyses synthetically the technical specialty and technical principle of MPLS VPN, resolved the MPLS arragement, MPLS VPN construction and the programming & setting of each VPN RD/RT of DCN network.With RT, we realized the communication of different VPN. According to our current network structure, it is feasible that the QOS scheme presented can ameliorate our Keywords:DCN,MPLS,QOS,TE(Traffic Engineering)...
