概述了保证QoS的MPLS网络生存性中各种保护和恢复策略,包括它们对QoS的不同要求、算法思想、应用领域、各自的优缺点等。将MPLS网络生存性与DiffServ模型结合起来,针对不同的业务要求选出不同的保证QoS的生存性方法。
This paper summarized various protection and restoration schemes of MPLS networks survivability with QoS guarantees, including their QoS requirements, algorithms, applications, pros and cons. It still integrated the survivability schemes of MPLS networks with DiffServ model in order to choose different survivability methods with QoS guarantees for different service classes.
