Planning Mpls Vpn For Ningxia Telecom Metropolitan Area Networks

In economic globalization today, Network economy rapidly expand, the number of Customer is much more Iardge.The partner increases, migration office workers also along with it sharp increase, Also has the new concept regarding the enterprise network's movement pattern. The Traditional enterprise network based on the fixed place's radial selector way; adapted the modern enterprise's demand with difficulty. Under such background, the long-distance office, between the company various Branch office, the company and the partner, the supplier, the company and the customer possibly must establish the interface channel to carry on the information transmission.The multi-agreement label exchanges (MPLS) is the present IP network core technologies, in the traffic engineering (Traffic Engineering), aspects and so on VPN, QoS obtains the widespread application, day by day becomes the important standard of large-scale IP network.MPLS and MPLS VPN are only one can satisfy the new generation private network service the solution technology, In the MPLS/IP network to provide VPN public business, By the business driven of operator and customer. On the one hand, can be carried out through the VPN business to provide new and differentiated services to the enterprise network and market penetration toachieve business growth, on the other hand, it can reduce the cost of Operation by one network, flexible bandwidth expansion to increase reuse and efficiency. For corporate customers, through the public network providers can set up private network, they also can speed up the construction of the network, reducing the cost of network construction. Expansion of bandwidth also be easy, and the complexity of the network operation also by greatly simplified. Compared to traditional VPN technology, MPLS VPN can automatically distribute the bottom of label. In the provision of services it more easy and more cheap than traditional VPN technology. At the same time; MPLS VPN can use some advanced features of MPLS technology. Easier to achieve inter-operator backbone network to ensure the quality of service, MPLS VPN can provide customers with routing technology based on the traditional VPN can not provide the type of business too. For example, support for the VPN address space multiplexing.Provides VPN in the MPLS/IP public network the service to receive the operator and the customer two aspect service actuation.The operator may through carry out VPN provision of service at the same time, the variation service and realizes the service to the enterprise network market penetration to grow, on the other hand may unite, the nimble band width multiplying through the network and raises the dilatancy efficiency to reduce transports the Uygur cost, MPLS VPN will become the major technique of the VPN network..The paper first introduced the VPN technology's background, elaborated the VPN types in detail; Next introduced the MPLS concept and the principle of work, and has analyzed and contrasted the work process of L2 MPLS VPN and the L3 MPLS VPN, then introduced designs Ningxia Telecom actual MPLS VPN application network, finally introduced the MPLS VPN superiority and the development.According to Study the VPN principle and the MPLS principle, We Designs Ningxia Telecom VPN network, solved the question that the users in the practical work to request to depend on the public network transmission private data and establishment confined network, accelerated the network construction, reduced the cost,safe reliable, simplified the network maintenance complexity greatly.
