　　Abstract:

　　For the purpose of establishing a virtual network on the IP network to cut the operating costs and reduce the unnecessary middle cycles of sales， realizing the non face-to-face immediate transactions with the online information and identity confirmation， the paper provided a secure， dependable and manageable way of realizing the virtual network which exclusively established a logical database channel for clients in MPLS VPN. Via the tests on the MPLS VPN?蒺s capability， dependability， security and the effect of cost reduction， it proved that businesses could receive prompt and accurate information based on the low-cost， highly capable and resource-efficient electronic information platform or E-commerce platform.
