不同网络技术融合的三种恢复机制的研究

Study on different network technology integration of the three recovery mechanisms

介绍三种由不同网络技术融合的内层恢复机制:光恢复和MPLS TE FRR、SONET/SDH保护和IP路由、MPLS TE FRR和IP重路由。从恢复动作和所需备份容量的角度分别讨论这三种融合技术。

This paper introduces the three network interlayer recovery mechanisms in form of different network technologies： Optical Restoration and MPLS Traffic Engineering Fast Reroute; SONET/SDH protection and IP Route; MPLS Traffic Engineering Fast Reroute （link protected） and IP Reroute. The above technolo- gies are discussed from the perspectives of a set of recovery actions and the required backup capacity.
