Research On MPLS-Based Multi-Service Bearing

In order to operate a mobile packet network and construct a mobile packet area VPN network which can be operable,administrable, roamable,profitable,the mobile packet domain network project of UNICOM adopted MPLS technology as the bearer for the services.As the expansion and extending of MPLS technology of the former 165 Internet,the project has fully utilized the resources of the existing network,and further improve existing network structure and the scheme of network access and security,thus form the best operation mode and foster the market of high speed mobile data service and layer 3 of VPN services.In the MPLS Multi-Service bearer project,the author is mainly responsible for the plan of network structure,the formulation of the network accesses scheme,and the realization of the layer 3 MPLS VPN, Including utilizing the Label Distribution Protocol as the signaling protocol of controller-layer to realize foundation of label switch path, realizing the distribution of private network label and the bearing of VPNv4 through MP-BGP.The author has formed a set of solutions of the MPLS multi-service bearer through further investigator.On the basis of the feasibility which has verified,the solution has already put into effect,and has favorably commented.
