基于负载分离的跨域虚拟专用网解决方案
Crossing-domain Virtual Private Network Solution Based on Load-separation
摘要
Abstract
When Virtual Private Network ( VPN ) constructed by Multiprotocol Label Switching ( MPLS ) and Border Gateway Protocol( BGP) is used in crossing domain platform,the label path can not be found and boundary devices are overloaded. Aiming at these problems,this paper analyses the fundamental reasons on the basis of label distribution and data forwarding plane. It brings forward two schemes,namely back to back project and single hop scheme based on EBGP to solve the problem of label distribution. However,the problem of overloading remains to be unsolved. Then this paper further proposes load-separation VPN solution based on multi-hop EBGP. In detail,the scheme improves the traditional VPN scheme by extending the existing protocols and modifying the systematic framework and brings forward specific configuration according to different network environment. This paper evaluates the performance of the schemes by comparing the different solutions through many indexes and the results indicate that load-separation VPN scheme is effective in realizing crossing-domain VPN and can solve both label distribution and overloading.关键词
