  • RFC 8231, Path Computation Element Communication Protocol (PCEP)—Extensions for Stateful PCE

  • RFC 8281, Path Computation Element Communication Protocol (PCEP)—Extensions PCE-Initiated LSP Setup in a Stateful PCE Model

  • Internet draft-ietf-pce-stateful-pce-07.txt, PCEP Extensions for Stateful PCE

  • Internet draft-crabbe-pce-pce-initiated-lsp-03.txt, PCEP Extensions for PCE-initiated LSP Setup in a Stateful PCE Model

  • Internet draft-ietf-pce-segment-routing-06.txt, PCEP Extensions for Segment Routing

  • Internet draft-ietf-pce-stateful-pce-p2mp-02.txt, Path Computation Element (PCE) Protocol Extensions for Stateful PCE usage for Point-to-Multipoint Traffic Engineering Label Switched Paths

  • Internet draft draft-cbrt-pce-stateful-local-protection-01, PCEP Extensions for RSVP-TE Local-Protection with PCE-Stateful (excluding support for bypass LSP mapping)
