[lmap] Feedback on draft-eardley-lmap-framework-01

["Weil, Jason" <[e-mail]>]

Here are my comments and questions on the draft:

Section 1. [use-cases]
Regulators: I would drop the word 'several' from this description. It reads as if regulators are targeting certain providers purposefully out of a group which is not typically the case.
---
The example given in Diversity seems to be another example supporting the interoperability benefits that come with the earlier bullet on Standardization.  A MA on a CPE router and another MA on a WiFi device behind the router or a MA running as a software client on a laptop/desktop might be  a better example?
---
Section 2.


   The MA functions are implemented either in specialised hardware or as
   code on general purpose devices like a PC, tablet or smartphone.  The
   Measurement Peer may be an LMAP device or a normal, non-LMAP device
   (for example if the MA measures the time for a DNS response or a
   webpage download from www.example.com).


A Measurement Peer is an LMAP functional element. It would seem to me that as long as an entity performs in the role of a Measurement Peer it would be considered an LMAP device whether or not it was purpose built for a single test or simply performing as a Measurement Peer based on its normal operational role such as a recursive resolver. As such I don’t believe a Measurement Peer would ever be considered a non-LMAP device if it was being used for a test by the MA.

Section 3.

3.2. Each MA may only have a single Controller at any point in time – The 'may' in this sentence makes me wonder where the constraint exists. Is the constraint that it must only take direction from a single Controller at any given time?
--
The topic on NAT an firewalls suggesting a pull model may be better as a separate constraint topic by itself.


Thanks,

Jason
