【摘要】 MPLS VPN是构建IP承载网的关键技术,利用MPLS VPN技术来搭建IP承载网有着诸多的优点及开阔的应用前景。该文在分析研究了利用MPLS VPN建设IP承载网的可行性的基础上,提出了状态机模型并用C语言进行实现。该模型可以将故障链路按照设计的处理模式进行VLL冗余备份上的主备虚链路间的快速切换,以此实现网络的稳定性。更多还原

【Abstract】 MPLS VPN is the key technology to construct IP supporting network.There are many advantages of the creation of IP supporting network by MPLS VPN technology which also has broad application prospect. This paper puts forward the state machine based on the study of the feasibility of constructing IP supporting network using MPLS VPN and uses C language to realize it.When the network link goes wrong,the solution can switch the state of standby PW of VLL quickly,which ensures die stability of network.更多还原
