[ NNSquad ] Re: Editorial Comment on "Entry level pricing"


Neil,

I agree with much that you're saying.  But part of what makes this so
complex is that we tend to often conflate different aspects of the
"network neutrality" debate into one rather large and dense lump.

For example, it's possible to separate -- to a significant extent --
the technical details from statements of societal policy.  E.g., "ISPs
should be free to conduct business however they see fit without any
regulation of any kind."  Or, "Reasonable regulation of ISPs is deemed
necessary and appropriate by society in keeping with society's
established interest in promoting the general welfare of its
citizens."

We also need definitions.  I believe we'd pretty much all agree that
"up to this speed" advertisements for Internet access services are
largely useless without additional data that usually is not available
to potential or current subscribers.  So how to define the "Internet
access experience" in a flexible but meaningful manner?  Not easy.
I'm reminded of Microsoft's "Vista Experience" rating that attempts to
suggest how well any given hardware configuration will run Vista.
I've found that rating to be essentially useless.  Coming up with a
consumer experience rating for Internet access would be even harder
(though, as we've heard previously on this list, there have been
proposals for more rigorous methodologies for such ratings).  Then
you're faced with how to get ISPs to accept such rating regimes absent
regulatory pressure, given that it isn't necessarily in an ISPs own
self-interest to reveal such details to consumers.

And you need measurements.  Old saying: If you can't measure it, it
isn't science.  Basically, in the Internet access world, there are
only two main ways to get network measurements.  One is to depend on
ISPs to do so fairly and effectively, and for them to make the
resulting data widely available.  But again, what's in it for them in
an unregulated, at best largely oligarchical environment?  Much of the
measurement data we'd really like to see to better understand what's
going on is often considered to be proprietary by ISPs.

Or computer users and the Internet sites that they frequent can take,
analyze, and share their own measurements.  This concept was a key
aspect of the network measurement meeting at Google last year, which
was the genesis for GCTIP ( http://www.gctip.org ).  I personally feel
that a bottom-up, consumer-led approach to this problem has the best
chance of success, but it's still not easy.  Not only are there a
variety of technical, logistical, and privacy issues involved, it can
also be quite nontrivial to analyze the resulting data without
knowledge of ISP internal topologies.  This can lead, for example, to
consumers assuming that they are being purposely blocked by an ISP,
when in reality an ephemeral routing or other temporary and purely
technical problem is at fault.  However, I do believe that these
issues could be overcome with sufficient dedication and effort, and I
still very much support the consumer-based approach.

In significant ways, getting Internet access service is like buying
drinks at a bar.  For any given drink, how much genuine booze is mixed
with how much water or other diluting agents?  How much do these
ratios vary from day to day and with time of day?  Does the bartender
tend to dilute the drinks more when the bar is crowded, rather than
buy enough extra liquor to keep the ratio up to standard even during
Happy Hour?  And how do you judge the ratio anyway?  Taste?  
Buzz level?  

It's easy enough to weigh a bag of M&Ms or count the number of tasty
chocolate-coated morsels that were provided.  But most any time that
we're dealing with products or services of a less physical nature,
especially when their "contents" can be easily altered or finessed,
it's all a much tougher proposition.
