Programming And Application Of Mpls Vpn Technology In Tianjin Power Integrated Services Digital Networks

Nowadays computer network has been an important part of the modern life. With the development of the technology of network, people want more requirements to the computer network:quick, security, cheap, quality and service. MPLS (Multi-Protocol Label Switching), as an important technology of NGN, is the best method of combine of the ATM and IP, which can meet these requirements very well. The important application of MPLS:VPN (Virtual Private Network) is becoming as the preferred scheme of building a computer network to more and more the providers of network service, large-scale enterprises and government, it becomes. However, comparing with the traditional private network, the deficiency of acknowledges to the security of MPLS VPN baffles its development and application, and actually, there exists some problems in the security of MPLS VPN. Now, it becomes a hotspot that how to settle these problems.This paper mainly at the engineering practice point of view, analyzes the present situation and existing problem of TianJin Power communication data network, and introduces the basic function of MPLS network, analyzing its in the construction principle and application modes. Through the analysis on the future business needs, proposes the establishment of Tianjin electric power communication integrated services digital network, and its after the establishment of the MPLS function was analyzed. This article specifically to work for MPLS VPN technology:Describe and introduce the related knowledge; Introduce choose MPLS VPN technical reasons, and the corresponding use planning; Introduce MPLS VPN technology in tianjin power network of the engineering applications; Analyze the development of MPLS in electric power communication.Integrated services digital networks for carrying business provides a high standard, high efficiency, high reliability transmission operation platform, realizing business bearing clear integration and can be well supported MPLS VPN network new technology for the future new communication application provides realizing basis and bearing safeguard. And, for the bearing MIS system, the collection control remote viewing system, management information system, and other important business provides more secure more efficient operation platform, dramatically improve the transmission efficiency of the business, and stability, satisfy the tianjin electricity company data service bearing demand.
