Re: [Pce] FW: I-D Action: draft-ietf-pce-pcep-flowspec-11.txt

Hi Adrian!

I looked at the diffs and I’m happy with the changes.  I’m clearing.

Thanks!

Alvaro.

Alvaro and Ben,

Very sorry for delaying this progress so much and possibly causing your
cache not only to be flushed, but the archive tapes sent to the fire-vault
in Utah.

The last issue you had remaining was that 5575bis has removed the
possibility of multiple Flow Specification components of the same type
being
present in one flow specification. We have aligned with this with two
changes:
- Added text to Section 7 saying:
As described in [I-D.ietf-idr-rfc5575bis]
where it says "A given component type MAY (exactly once) be present
in the Flow Specification," a Flow Filter TLV MUST NOT contain more
than one Flow Specification TLV of the same type: an implementation
that receives a PCEP message with a Flow Filter TLV that contains more
than one Flow Specification TLV of the same type MUST respond with a
PCErr message with error-type TBD8 (FlowSpec Error), error-value 2
(Malformed FlowSpec) and MUST NOT install the Flow Specification.
- Section 8.4 has been rewritten to mainly say "use separate Flow
Specification Objects for separate flow specifications"

This -11 revision picks up all other outstanding comments and nits.

Best,
Adrian

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the Path Computation Element WG of the IETF.

Title : PCEP Extension for Flow Specification
Authors : Dhruv Dhody

Filename : draft-ietf-pce-pcep-flowspec-11.txt
Pages : 37
Date : 2020-10-05

Abstract:
The Path Computation Element (PCE) is a functional component capable
of selecting paths through a traffic engineering network. These
paths may be supplied in response to requests for computation, or may
be unsolicited requests issued by the PCE to network elements. Both
approaches use the PCE Communication Protocol (PCEP) to convey the
details of the computed path.

Traffic flows may be categorized and described using "Flow
Specifications". RFC XXXX defines the Flow Specification and
describes how Flow Specification Components are used to describe
traffic flows. RFC XXXX also defines how Flow Specifications may be
distributed in BGP to allow specific traffic flows to be associated
with routes.

This document specifies a set of extensions to PCEP to support
dissemination of Flow Specifications. This allows a PCE to indicate
what traffic should be placed on each path that it is aware of.

The extensions defined in this document include the creation, update,
and withdrawal of Flow Specifications via PCEP, and can be applied to
tunnels initiated by the PCE or to tunnels where control is delegated
to the PCE by the PCC. Furthermore, a PCC requesting a new path can
include Flow Specifications in the request to indicate the purpose of
the tunnel allowing the PCE to factor this into the path computation.

RFC Editor Note: Please replace XXXX in the Abstract with the RFC
number assigned to draft-ietf-idr-rfc5575bis when it is published.
Please remove this note.
