Design And Impiementati On Of E-Government Affairs Internet Backbone Network Based On Mpls Vpn Technology

The rapid development of computer network technology as well as in the government administration in a wide range of applications, makes E-Government affair has become the focus of attention of governments and the development of the national main goal. The development of E-Government affairs, first of all to build up and down through, horizontal and vertical interconnection, perfect function, high stability, safe and reliable, unified E-Government backbone network, support to cross a region, cross functional business interoperability, meet various application needs.MPLS VPN is based on multi protocol label switching technology, is in the network routing and switching device using MPLS technology, combined with the traditional routing technology to realize the IP label exchange virtual special network IP VPN, its high safety and reliability, strong management capabilities, flexible control strategy and scalability, has as telecom level E-Government network construction is an important research direction.This paper introduced the E-Government affairs related to the theory, a comprehensive study on the E-Government affairs Internet backbone network construction demand, in-depth analysis of the E-Government affairs Internet backbone network key technology, put forward based on MPLS VPN bearing multi service system of Telecom E-Government backbone network architecture. In the MPLS VPN technology theory on the basis of thorough research, taking a provincial E-Government affairs Internet backbone network construction as the background, proposed based on MPLS VPN technology in E-Government backbone network design and realization thought, further elaborated the BGP, OSPF and MPLS VPN technology applied to large electronic government network platform construction, can be better meet the E-Government centralized, integrated services, collaborative e-government development trend of demand, realized in the unity government network platform based on IP data, voice and video communication, to large E-Government network platform construction has important direct sense.
