Research And Implement On An Access Adaptor Of MPLS VPN Network

MPLS_VPN(Multiprotocol Label Switching Virtual Private Network) is a novel and practical network technology. VPLS(Virtual Private LAN Service) is the second layer of the realization of MPLS_VPN. MPLS_VPN can be like traditional VPN that each user sites in different regions of the composition of the virtual private network a logically. Connected by network operators to the tunnel, MPLS_VPN can access the network users to provide LAN like link effect. It also has the characteristics of some of the more traditional VPN better: low data overhead, lower setup costs, simple maintenance and better safety.The thesis research mainly in 3 aspects below:1. The actual demand of the MPLS_VPN related protocol fully study and analysis of user, determine the target device function. Find the basic hardware requirements of access equipment in MPLS_VPN under the network condition. To select the suitable hardware equipment, combined with the EDA design technology, design a kind of that meet user needs and has certain development potential of MPLS_VPN access hardware platform, provide the basis for the upper application.2. Comparative study of a variety of domestic and foreign MPLS_VPN, especially the access technology of VPLS network, the actual situation and needs of the reference of network users, and studies the characteristics and data format of VPLS network access, formulates the practical scheme, the design and implementation of a MAC based in MAC technology, at the same time have access platform user isolation, fast access, simple configuration, optimization of network and other excellent characteristics.3. Set up the testing environment using a small utility network, and take a series of tests proved the feasibility and effectiveness of the platform. At present the access device has been formally applied to the target user network,obtains the very good use effect. Finally, discussion on the optimization method of the application and the way to realize other applications. A large number of users to achieve static routing configuration in a test environment, to achieve the user free access function, reduces the address storage above public access device 90%, a reduction of more than90% configuration time and more than 70% of the cost of laying lines, to achieve excellent practical effect.The scheme in this thesis based on the design of access adapter device, can effectively reduce the network structures, the management process configuration operation, to reduce the technical difficulty of maintenance and management, so as to effectively reduce the opening of the network cost of operation and maintenance. In providing users with efficient at the same time connection also protect users of existing equipment value. The scheme of hardware platform has greatly expanded, the application can achieve a variety of MPLS_VPN technology on the platform.
