Abstract
A communications method enables a path computation element (PCE) to notify path computation clients (PCCs) about the shared resources of independent label switch paths by allowing a PCE to send an association object with a new association type to PCC. A PCE Communication Protocol extension that associates label-switched paths (LSPs) whose ingress, or egress, or both ingress and egress are different for resource sharing to avoid path computation failures or duplicate allocation of resources during common links for new LSPs created during an update of end-to-end (E2E) LSP. The PCC employs Resource Reservation Protocol (RSVP) for LSP signalling, PCC forwards path message information along with association object to the RSVP for LSP signalling. The RSVP uses the association object in its reservation message for LSP setup.
