Mpls-based E-government Network Technology Research

With the further development of E-Government, the demand for sharing of government information by government branches and public is standing out. With the large-scale construction of basic resources for E-Government for several years, plenty of applications of deep levels such as government information digging, management of E-Government knowledge and so on will come into the field of E-Government gradually which will perform more and more important functions in these aspects as following: optimizing decision process, improving decision method, accelerating decision speed, enhancing decision quality, etc.Currently, traditional DDN or 2M SDH lines are widely used in the network construction of E-Government around our country, while some areas with better economic conditions build the network connections directly by fibers. With the advancement and integration of E-Government applications, the traditional IP-based network cannot satisfy the demand for complex applications.Therefore, it is necessary to introduce MPLS technology in networks for E-Government.In this thesis, the design and development of a MPLS VPN-based network for E-Government is introduced, which is guided by the theory and practice for software engineering. First, the MPLS VPN-based network for E-Government adopts the tag switching technique to realize the data separation among different clients and departments, solving the QoS/CoS problem which has been confusing the traditional IP networks by separating service systems. Second, MPLS VPN-based network for E-Government provides the capability of flow capacity engineering to optimize the allocation of network resources, automatically and quickly renovate network failures and enhance the usability and reliability. At last, the MPLS VPN-based network for E-Government has the advantages such as flexible networking, convenient extending, security, and so on.The MPLS VPN-based network for E-Government provides a safe and reliable transmitting base for realizing E-Government, promoting the change of administrative functions from traditional government to modern government, facilitating the...
