Abstract
The present disclosure provides system, method and apparatus for implementing fast reroute (FRR). The present disclosure provides a mechanism to associate working LSPs with a FRR LSP to protect against the node/link failures and can switch the traffic immediately upon LSP failure. Further, the present disclosure enables to communicate the status of FRR in use to the PCE so as to have centralized control over the FRR mechanism.
