NSP Procedures on Receiving a PCRpt Message for a PCE

  1. The NSP confirms the bandwidth reservation and updates its LSP database. The PCC and PCE are synchronized at this point.
  2. The NSP reports the PLSP-ID/Tunnel-ID to the application, for example NSD, or to the operator that uses it in the specific application that originated the request.
  3. The PCE can perform updates to the path during the lifetime of the LSP by using the PCUpd message in the same way as with a delegated PCC-initiated LSP.
