Internet Engineering Task Force (IETF) S. Sivabalan Request for Comments: 8408 Cisco Systems, Inc. Category: Standards Track J. Tantsura ISSN: 2070-1721 Nuage Networks I. Minei Google, Inc. R. Varga Pantheon Technologies SRO J. Hardwick Metaswitch Networks July 2018 Conveying Path Setup Type in PCE Communication Protocol (PCEP) Messages Abstract A Path Computation Element (PCE) can compute Traffic Engineering (TE) paths through a network; these paths are subject to various constraints. Currently, TE paths are Label Switched Paths (LSPs) that are set up using the RSVP-TE signaling protocol. However, other TE path setup methods are possible within the PCE architecture. This document proposes an extension to the PCE Communication Protocol (PCEP) to allow support for different path setup methods over a given PCEP session.

Standards Track [Page 2] RFC 8408 PCE Path Setup Type July 2018 1. Introduction [RFC5440] describes the PCE Communication Protocol (PCEP) for communication between a Path Computation Client (PCC) and a Path Computation Element (PCE) or between a PCE and a PCE. A PCC requests, from a PCE, a path subject to various constraints and optimization criteria. The PCE responds to the PCC with a hop-by-hop path in an Explicit Route Object (ERO). The PCC uses the ERO to set up the path in the network. [RFC8231] specifies extensions to PCEP that allow a PCC to delegate its LSPs to a PCE. The PCE can then update the state of LSPsShow full document text
