Abstract:

   The Stateful PCE extensions allow Stateful control of Traffic
   Engineering (TE) LSPs using PCEP for RSVP-TE and Segment Routing (SR)
   (for both MPLS and IPv6 Data planes) for both PCE-Initiated and PCC-
   Initiated LSPs.

   Extensions to the Path Computation Element Communication Protocol
   (PCEP) for MPLS-TE Label Switched Path (LSP) Automatic Bandwidth
   Adjustments with Stateful PCE are defined in RFC 8733.  It defines
   the AUTO-BANDWIDTH-ATTRIBUTES TLV and a set of sub-TLVs for each of
   the attributes.  The sub-TLVs are included if there is a change since
   the last information sent in the PCEP message.  However, it lacks a
   mechanism to remove an attribute identified by the sub-TLV
   explicitly.

   This document updates RFC 8733 by defining the behaviour to remove an
   attribute explicitly.  In addition, this updates allow applying this
   PCEP extensions to SR-TE LSPs (for both MPLS and IPv6 Data planes),
   in addition to MPLS-TE LSPs.
