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 document updates RFC 8733 by applying the PCEP
extensions to SR-TE LSPs (for both MPLS and IPv6 Data planes), in
addition to MPLS-TE LSPs.
