摘　　要：提出了自动交换光网络(ASON)的生存性机制及GMPLS保护模式,并以快速重路由故障恢复为背景,结合缓存技术和SBBP机制提出一种网络保护和故障恢复模型,该模型提供了流量的QoS保证并解决了流量切换所带来的报文丢失及失序问题。The principle of ASON survivability and GMPLS protection model was first proposed. Then a net- work protection and fault recovery model was established. This model is based on rapid re-routing fault recovery combined with caching technology and SBBP mechanism.This model can ensure the QoS of traffic and avoid the data packet discarding and disorder when traffic switch.
