Abstract
Methods, systems, and computer readable media for computing label-switched data communication paths are disclosed. An example method includes receiving, by a path computation element (PCE) implemented on at least one processor, synchronization status information for routing nodes in a label-switched network. The method includes receiving, by the PCE, a request for a label-switched path (LSP) from a client. The method includes determining, by the PCE, a responsive LSP based at least in part on the synchronization status information. The method includes sending, by the PCE, an explicit route object (ERO) for the responsive LSP to the client.
