摘　　要：基于ATM/MPLS技术的通信网络是承载宽带多媒体业务的综合平台。为了对承载业务进行抗毁保护,对ATM的最基本的1+1、1∶1、m∶n抗毁保护结构进行了研究和总结。同时结合网络传输层,如:PDH、SDH、WDM、MPLS的保护和应用层业务,如:IP、电路交换、以太网和帧中继的抗毁迂回策略,提出了ATM的多层次抗毁自恢复组网结构,为ATM的应用研究提供了借鉴。Communications network based on ATM/MPLS technology is an integrated platform bearing wide-band multi-media services. For survivability and self-restoration of services, this paper investigates and summarizes basic 1 ＋ 1,1：1, and m：n survivable protection structures for ATM network. A multi-layer survivable self-restoration networking structure for ATM networks is put forward by combining transmission layer protection such as PDH, SDH, WDM and MPLS with application service remuting scheme such as IP, STM, LAN, Frame Relay, so as to provide technical reference for application research on ATM networks.
