Re: [lmap] What is broadband?

[<[e-mail]>]

the 'A' in lmap doesnt stand for anything (somewhere lost in the mists of history... it didnt seem sensible to change the abbreviation before the BoF, since people have got used to the term)

consumer and enterprise wired broadband certainly of interest to me. that includes the network beyond the access (BRAS, peering point etc).  so a "registry" of reference points in the network seems like work that needs to be done [tools.ietf.org/html/draft-morton-ippm-lmap-path as first attempt]

Subject: Re: [lmap] What is broadband?

I believe that Henning had commented at some point that the LMAP definition he contemplated had "architecture" as the 'A' element but certainly access is an important piece.  I think one of the problems that has been discussed also on the LMAP and our FCC Next-Gen lists is that a complete view of LMAP performance measurements would implicate elements from the user's laptop, through wireless and other local LAN, carriers access networks, Tier 1 and other peering networks, the application host side and everything in between.  Clearly there would be a lot of technologies included within that functional scope.

For reference, in the FCC Measuring Broadband America Program we focused on measurement from the consumers' broadband modem through the carriers network to where it connects to a tier one peering point.  LMAP should be able to address the broad mix of other use cases that would have a mix of other elements and motivations.

The word "access" should be key here as part of the definition provided we are talking about an Internet service, which is the second component.   I don't really  think we are building tests that won't work on smaller pipes so questioning if it really 'broadband' or not is correct IMO.

Dear all,

I started to review the drafts, and I will start posting a few questions to the list.
Open questions, clarifying questions, in order to generate some discussions.
Disclaimer: I have not yet read the entire list archive. Apologize in advance if some points have been discussed already.

Here is my first question. What is broadband in the LMAP context?
Is it DSL, cable, ETTH, Fiber to the home?  Is LMAP technology independent?
And I see also "enterprise edge router", "cellular data or satellite" in draft-schulzrinne-lmap-requirements. In or out?
Or do we have in mind a phase approach, starting with the "enterprise edge router" first, and then home network?

Speaking for the network I operate, I'm very much an advocate of saying that "Enterprise Edge Router" is "in-scope".  We would very much benefit from a standards-based measurement enablement and collection regime vs. mostly proprietary, and non-scalable, approaches that exist today.

This is not to diminish the importance of similar test capabilities for residential broadband use-cases.  We absolutely need to work on those, as well.

With respect to priority, my hope is that we do not have to choose to prioritize one over the other.  Rather, I would hope that both can be developed in parallel, because both -- at least, IMO -- have a substantially overlapping set of requirements/features.

My $0.02,

Interestingly, I don't know what A stands for in LMAP, if it stands for something.
According to http://trac.tools.ietf.org/bof/trac/wiki/WikiStart, the A doesn't stand for anything.
However, looking at the different draft titles, there is some confusion.

   draft-linsner-lmap-use-cases-0 title is Large-Scale Broadband Measurement Use Cases
   draft-schulzrinne-lmap-requirements-00.txt title is Large-Scale Measurement of Broadband Performance
   draft-boucadair-lmap-considerations-00, Large scale Measurement of Access network Performance (LMAP):
      Requirements and Issues from a Network Provider Perspective

Some more discussions, on the mailing list or during the BoF, on this topic would be appreciated.

Regards, Benoit
