A new Request for Comments is now available in online RFC libraries. RFC 8231 Title: Path Computation Element Communication Protocol (PCEP) Extensions for Stateful PCE Author: E. Crabbe, I. Minei, J. Medved, R. Varga Status: Standards Track Stream: IETF Date: September 2017 Mailbox: edward.crabbe@oracle.com, inaminei@google.com, jmedved@cisco.com, robert.varga@pantheon.tech Pages: 57 Characters: 128096 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-pce-stateful-pce-21.txt URL: https://www.rfc-editor.org/info/rfc8231 DOI: 10.17487/RFC8231 The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Client (PCC) requests. Although PCEP explicitly makes no assumptions regarding the information available to the PCE, it also makes no provisions for PCE control of timing and sequence of path computations within and across PCEP sessions. This document describes a set of extensions to PCEP to enable stateful control of MPLS-TE and GMPLS Label Switched Paths (LSPs) via PCEP. This document is a product of the Path Computation Element Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol. Distribution of this memo is unlimited. This announcement is sent to the IETF-Announce and rfc-dist lists.
