基于企業在IP網上建立專用虛擬網絡，降低運營成本，減少銷售中間環節，實現非面對面的實時交易，確認網上信息和身份真實性之目的，給出了在MPLS VPN網上為用戶建立專用的邏輯數據通道，構建一種安全、可靠、可管理的虛擬專用網絡的實現方法。通過進行MPLS VPN的高性能、高可靠性、安全機制和低成本的實驗，得出了企業可得到及時準確的信息，擁有低成本、高性能、資源合理利用的電子信息平臺或電子商務平臺的結論。

　　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.
