Thanks to the extensions defined in [I-D. draft-ietf-pce-pce- initiated-lsp] and [I-D.draft-ietf-pce-remote-initiated-gmpls-lsp], it is possible to initiate LSP Setup in a Stateful PCE Model for MPLS and GMPLS scenarios. This document complements previous documents by providing an explanation of the use cases to use such PCEP extensions. This document presents single layer and multi-layer use cases, where not only the PCE is involved, but also other modules defined in IETF, such as Virtual Network Topology Manager and Provisioning Manager.
