Re: [Pce] WG Adoption of draft-li-pce-pcep-pmtu-05

[Pengshuping (Peng Shuping)]

Hi Dhruv,

As an author of this draft, I would like to thank the Chairs of both WGs for 
the guidance. We will post the PCE document and start drafting the SPRING one.

Thank you!

Best Regards,
Shuping

Hi WG,

Thanks for providing your feedback and discussion on the adoption of this draft.

The discussion on this thread as well as a chat with the SPRING chairs confirms 
the need for a document in the SPRING WG that can be referred to by the 
protocol extensions in PCE (and IDR). There is also no opposition to the actual 
protocol work in PCE.

Thus, the chairs conclude the adoption poll and adopt this I-D in the PCE WG. 
The chairs also ask the authors (and whoever is willing to contribute) to 
produce a document in the SPRING WG in parallel and continue the discussion on 
the SPRING mailing list. Post-adoption, the PCE document would need to remove 
any duplicate content and refer to the spring document instead.

Thanks!
Dhruv & Julien

Why not? What needs to be fixed before or after adoption? Are you willing to 
work on this draft? Review comments should be posted to the list.

[Pce] I-D Action: draft-ietf-pce-pcep-pmtu-00.txt

[internet-drafts]

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   : Support for Path MTU (PMTU) in the Path Computation 
Element (PCE) communication Protocol (PCEP)
Authors : Shuping Peng
  Cheng Li
  Liuyan Han
  Luc-Fabrice Ndifor
Filename: draft-ietf-pce-pcep-pmtu-00.txt
Pages   : 11
Date: 2022-05-05

Abstract:
   The Path Computation Element (PCE) provides path computation
   functions in support of traffic engineering in Multiprotocol Label
   Switching (MPLS) and Generalized MPLS (GMPLS) networks.

   The Source Packet Routing in Networking (SPRING) architecture
   describes how Segment Routing (SR) can be used to steer packets
   through an IPv6 or MPLS network using the source routing paradigm.  A
   Segment Routed Path can be derived from a variety of mechanisms,
   including an IGP Shortest Path Tree (SPT), explicit configuration, or
   a Path Computation Element (PCE).

   Since the SR does not require signaling, the path maximum
   transmission unit (MTU) information for SR path is not available.
   This document specify the extension to PCE communication protocol
   (PCEP) to carry path (MTU) in the PCEP messages.

Hi Aijun,

Thank you for your suggestions.

Since this draft is going to be refined considering the new draft being built 
in SPRING, the current uploaded draft is not changed accordingly. Please find 
more responses in line below.

Best Regards,
Shuping

Hi, Dhruv:
I have read this document and support it adoption.
Some suggestions for the current contents are the followings:

1. The proposal in this draft is easy to understand, It is better to 
simplify the “Introduction” part.

Shuping> Yes, this part will be simplified.


2. There should be one section about “Procedures for the Path MTU 
calculation”, which can include the some contents in section 3.1, section 3.2, 
section 3.5

Shuping > Yes, this section is needed. We will consider where to put it.


3. Section 3.3 and 3.4 should be put in one independent section, such as 
“Application of the Path MTU Metric”?

Shuping >  We will consider this suggestion. Thank you!
