Construction And Application Of VPN BGP/MPLS Technology

With the rapid development of enterprise network scale, the enterprise in order to cater to the development direction of the network, it is needed to build a VPN network with expansibility, easy management and easy maintenance. The VPN constructed by the traditional technique of virtual private network can not satisfy the need of the development of the enterprise network. In this paper, according to the needs of enterprise development, this paper presents the technology of MPLS (multi protocol label switching) and BGP (border gateway routing protocol) technology to optimize and adjust the traditional VPN network, and puts forward the existing traditional VPN has been unable to meet the development of the enterprise network, and combined with the reality of G enterprise development needs to make a detailed plan and formulation of the scheme. The main contents of this thesis are as follows:At first, we analyze the construction of enterprise informatization in our country, and we find that the traditional VPN network can not adapt to the rapid development of enterprises. According to the development of enterprise network, we analyze the following:traditional VPN can not meet the business needs of network expansion; the enterprise is not easy to manage the network in the traditional VPN construction; maintenance personnel in the enterprise network maintenance is more complicated, not Yi Weihu; existing network in the enterprise data transmission process is a security problem. Combined with the above problems, we propose to build a brand new enterprise network through MPLS and BGP technology. In the scheme design, we first introduced the selection of MPLS and BGP technology, the IPv6 is now more popular, the problem is analyzed, and the corresponding solution is put forward, which guarantees the feasibility of the optimization scheme.Secondly, through the introduction of domestic and international BGP and MPLS technology, the paper puts forward the reform scheme of G enterprise network. In order to guarantee the implementation of the scheme, we first make a detailed plan of the enterprise network equipment name, the IP address, BGP routing, etc., and establish the test environment. Through the test we can fully prove that the MPLS andVPN technology to build the BGP network than before G enterprise use of the traditional VPN construction of the network is more secure, more stable, running more stable, fully meet the needs of G enterprise development in the next 5 years.Finally, through the summary of the design of this project, we put forward the optimization of the scheme design and the OSPF protocol, and propose the IS-IS protocol is more suitable for the development of G enterprise network, we put forward the suggestion on the implementation of the design scheme, transmission resource optimization and operation team.
