Re: [Pce] WG Adoption of draft-chen-pce-pcep-ifit-06

[Adrian Farrel <[e-mail]>]

Hi,

 

I read through this draft as part of the adoption poll.

 

I found it quite hard to work out from the Abstract what the purpose of

the document is. The Introduction is a little more informative, but also

quite hard work.

 

It turns out, when you read the document, that two things are being

defined:

1. A set of attributes to allow a PCE to instruct a PCC as to which IFIT

   behaviours it should enable on a path.

2. A capabilities flags so that a PCC can indicate which IFIT functions

   it supports.

 

I think the Abstract might usefully read as follows.

 

   In-situ Flow Information Telemetry (IFIT) refers to network OAM data

   plane on-path telemetry techniques, in particular In-situ OAM (IOAM)

   and Alternate Marking.

 

   This document defines PCEP extensions to allow a Path Computation 

   Client (PCC) to indicate which IFIT features it supports, and a Path 

   Computation Element (PCE) to configure IFIT behavior at a PCC for a

   specific path in the stateful PCE model.

 

   The PCEP extensions described in this document are defined for use

   with Segment Routing (SR). They could be generalized for all path 

   types, but that is out of scope of this document.

 

The Introduction might also usefully change in that way.

While I appreciate that the authors are primarily concerned with SR, I

think the WG should carefully consider taking the authors at their word

and pursuing the generalisation to all path types. That can't be much

additional work, and it would surely make sense to get the solution to

be generic from day one.

 

---

 

Please move the requirements language from the front-matter to its own

section (probably 1.1).

With the clarification of the intent of the document, I would support 

the working group working on this document, and it could be adopted.

 

Regards,

Adrian
