Re: [aqm] adoption of draft-white-aqm-docsis-pie-01

Hi,

You have an interesting process to encourage mic comments. ;)

Reviewed version: "draft-ietf-aqm-docsis-pie-00".

I did read the document, looks good from clarity perspective. The changes compared to PIE also look reasonable.

I cannot judge however how well the algorithm estimates PIE behavior or how good is it in general. I did not read the references.

Questions:
-" 3.2. Departure rate estimation" Pie implements a rate estimator because it might be used with Fair Queueing schedulers. You write " Third, in the significant majority of cases, the departure rate, while variable, is controlled by the modem itself via the pair of
token bucket rate shaping equations described". I assume that Fair Queueing is either not implemented then in the modem or it is rarely used together with PIE. Is it so, or do I misunderstand this? Please clarify this for me and also in the document, if you think that is applicable! 

I propose the following updates (all optional in my view but it would definitely help the reader):
-State that the "[DOCSIS*" documents do contain simulation results. It was not clear for me from just reading the draft.
-Write a short (<0.5 page) summary of the simulation results in the appendix.

Cheers,
Szilveszter

Hi group,

as there haven't been any objections, but some indications of support on the list, and based on the responses in the IETF92 meeting in Dallas, we chairs think this document can be adopted as WG-item at this time.

Greg, can you please upload the most recent version as draft-ietf-aqm-docsis-pie-00?

Also, as mentioned in the meeting, and to make true of my promise, I would like to invite the following individuals to review this draft, once the updated version becomes available.

Mikael Abrahamsson
Dave Dolson
Szilveszter Nádas

Mostly everybody else who has commented during the meeting is already assigned to other documents (Nobody will be left out :)

Thanks,
  Richard (co-chair)
