Abstract
In order to improve the reliability of IP Radio Access Networks (IP RAN)and reduce the losses caused when they break down,the existing network protection technologies,such as LSP protection,PW redundancy protection,VPN FRR, VRRP are studied.The network deployment structures commonly used in present projects are investigated and a general model containing access layer,convergent layer and core layer summarized.On the basis of analyzing faults occur in various situa-tions,a scheme that integrates multiple technologies is designed so as to ensure the normal operation of the networks,impro-ving network reliability and providing certain reference for network deployment.关键词
