Abstract
A path control element (PCE) is provided, including a processor and a non-transitory computer readable storage medium coupled to the processor. The storage medium stores programming for execution by the processor, wherein the programming, when executed by the processor, configures the PCE to receive a request for a path of a unicast or multicast label switching path (LSP), determine a primary path and a secondary/local protection path through a plurality of nodes in a label switched network, and provide the primary path and the secondary/local protection path to the plurality of nodes.
