RFC 8800 Title: Path Computation Element Communication Protocol (PCEP) Extension for Label Switched Path (LSP) Diversity Constraint Signaling Author: S. Litkowski, S. Sivabalan, C. Barth, M. Negi Status: Standards Track Stream: IETF Date: July 2020 Mailbox: slitkows.ietf@gmail.com, msiva282@gmail.com, cbarth@juniper.net, mahend.ietf@gmail.com Pages: 21 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-pce-association-diversity-15.txt URL: https://www.rfc-editor.org/info/rfc8800 DOI: 10.17487/RFC8800 This document introduces a simple mechanism to associate a group of Label Switched Paths (LSPs) via an extension to the Path Computation Element Communication Protocol (PCEP) with the purpose of computing diverse (disjointed) paths for those LSPs. The proposed extension allows a Path Computation Client (PCC) to advertise to a Path Computation Element (PCE) that a particular LSP belongs to a particular Disjoint Association Group; thus, the PCE knows that the LSPs in the same group need to be disjoint from each other. 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.
