Ben, Jari,
thanks for the follow-up, here are some further proposals

OLD
o Understanding the quality experienced by customers. Alongside
benchmarking competitors, gaining better insight into the user's
service through a sample panel of the operator's own customers.
The ISP requires a performance viewpoint of the end-to-end
perspective, which includes: home/enterprise networks; peering
points; Content Delivery Networks (CDNs); etc.
PROPOSED NEW
o Understanding the quality experienced by customers. The network
operator would like to gain better insight into the end-to-end performance
experienced by its customers. This could incorporate home and enterprise
networks, and the impact of peering, caching and Content Delivery Networks
(CDNs).

OLD
The panel needs to include a representative sample for
each of the operator's technologies (fiber, Hybrid Fibre-coaxial
(HFC), DSL...) and broadband speeds (80Mb/s, 20Mb/s, basic...).
PROPOSED NEW
The panel needs to include a representative sample of the operator's
technologies and broadband speeds. For instance it might encompass speeds
ranging from sub 8Mbps to over 100Mbps.
> I also suggest dropping "(say)" and and the sentence-starting "So..." from
> later in the paragraph.
agreed.
OLD
The operator would like the end-to-end view of
the service, rather than (say) just the access portion. So as well as
simple network statistics like speed and loss rates, they want to
understand what the service feels like to the customer.
NEW
The operator would like the end-to-end view of
the service, rather than just the access portion.
>> - 3.1, 1st para:
>>
>> Can you provide a definition or reference for "mean opinion score"?

> Not addressed.
If a reference is really needed, then i guess
http://en.wikipedia.org/wiki/Mean_opinion_score will do.
>> -- 3.2:
>> Overly complex sentence structure. Consider breaking into bullet lists.
>> Something seems messed up near " along the lines..." . Maybe a cut and paste
>> error?
> The bullet list improves things. Bullet 2 still contains a list of examples
> in the form of comma-spliced sentences.
OLD
o Understand the impact of IPv6 before it makes it available to
customers (will v6 packets get through, what will the latency be
to major websites, what transition mechanisms will be most
appropriate?)
PROPOSED NEW
o Understand the impact of IPv6 before it is made available to
customers. Questions such as these could be assessed: will v6 packets get
through? what will the latency be
to major websites? what transition mechanisms will be most appropriate?
>> -- 4.1, 1st para, last sentence: "... mandate transparent information made
>> available..."
>> Should that be "... be made available..."?
> Fix attempted, but new typo "imade" introduced".
OLD
In some jurisdictions regulators mandate that transparent
information imade available about service offers.
NEW
In some jurisdictions regulators mandate that transparent
information be made available about service offers.
>> -- 4.2, 3rd paragraph:
>> Can you offer a definition for "probes"?
> Not addressed.
I don't want to address this one. Formal terminology is in the LMAP framework,
including the definition of "measurement agent". In this document we used the
more informal term "probe", as it seems easy to understand without a formal
definition. Since this use cases doc might have a wider readership, we wanted
to avoid terminology and just give the reader the motivations and usages of
LMAP measurement information.
