Abstract
The present invention provides a novel method for hierarchy of preplanned protected path for both node and link failure in the realm of Carrier Ethernet Technology. In the event of failure in a hierarchy, the traffic is switched from work (primary) path to protected (secondary) path. If such path does not exist within a given hierarchy then traffic is routed through multiple hierarchies until SLA is met or no path exists. Hierarchies make the network fault resilient.
