Assuming you're referring to a soup-to-nuts physical layer network,
building one's own infrastructure isn't a panacea, and it is not even
very often a doable proposition for organizations outside of the
government and for companies outside of the Fortunes.

Taken to the extreme, customer owned networks, if used as the sole
source of transport, defies both the type of robustness that we seek -
unless multiple networks per customer are built - and the very form of
inter-working demanding of any-to-any end-to-end reach.

So, unless it's a situation where great economies can be achieved in
support of applications that are relatively local to (or resident solely
within the borders of) an enterprise, maybe it's not the end all and be
all that we sometimes make it out to be. For a University and Research
Consortium, fine. For a forty-state branch banking network that
must reach 42,347 end points, with most of those end points producing
traffic for a single T1 or T3 line, or even a GbE line over an extended
distance, it would appear on the surface "not," although each point
solution requires its own evaluation. Volume discounts, the degree of
diversity required and security issues all come into play, to name just
three areas of concern.

Rather, private builds are great for spot solutions, even very large
ones, that are relatively constant between two or more points when those
points are, likewise, constant and not constantly being relocated. But
IMO they do little in the way of extending reach beyond the borders of
the enterprise. For service providers, on the other hand, it's more of a
financial consideration, assessing tradeoffs against perceived future
pricing trends and traffic volumes. Again, to buy, rent or build is
something that can only be determined at the time of need, and based on
the particulars of the enterprise or service provider.

That said, the situation I addressed initially highlights a case where the
market had already begun taking care of some of the critical needs of
diversity and redundancy for the universe of North American (or at least
US) users, which are now about to be trashed in order to satisfy the
goals of two corporate entities.

Does this make any sense? Of course not. But viewed against the backdrop
of this past week's FCC releases, the trend, despite how irrational and
ludicrous it may appear, is ringing clear as day. And so it goes ...

Re: Of Fiber Cuts and RBOC Mega-mergers

2005-08-08 Thread sgorman1


The unfortunate part of all this is there is a demand for diversity, especially 
from the financial and government sectors.  One of the big problems is that 
clients seldom know which providers or combinaiton of providers give them the 
most diversity.  There are some intersting ways to claculate the optimal set of 
providers by price and diversity, but getting the data is quite difficult.  
Sometime large clients like the US government can leverage providers into 
divulging routing and right of ways, but is definately the exception.  Even 
from our rough analyses there are several areas of heavily shared colocation.  
Sounds like the problem is getting worse and not better.

FCC Bans VoIP Services Blocking

2005-08-08 Thread Fergie (Paul Ferguson)

Via Red Herring:

[snip]

While much of the reaction to Friday’s U.S. Federal Communications Commission 
ruling has been focused on ISPs, a policy statement issued as part of the 
commission’s deregulation of DSL services could add much-needed legal 
protection for VoIP carriers such as Vonage and Skype.

The FCC issued a statement that it does not want the newly freed DSL providers 
and cable operators to use their total control of their networks to interfere 
with the access rights of direct competitors such as VoIP providers.

A policy statement does not have the legal teeth of a rule, but it does put 
telecommunications carriers and cable operators on notice that there are still 
aspects of broadband services delivery in which the FCC reserves the right to 
meddle.

"We need a watchful eye to ensure that network providers do not become Internet 
gatekeepers, with the ability to dictate who can use the Internet and for what 
purpose," said Michael J. Copps, one of two democrats on the FCC panel. 
"Consumers do not want to be told that they cannot use their DSL line for VoIP, 
for streaming video, to access a particular news web site, or to play on a 
particular company’s game machine."

What was the actual cost of this outage to operators in SLA credits?
Perhaps it's just a function of economics: it's cheaper to plan for
the 3 fiber cuts per 1000 route miles per year (or whatever the silly
rate was I came across somewhere) and hand out credits than actually
engineer physical redundancy.

But seriously, has anyone quantified what this or similar cuts *actually cost*?

So what I understand from your slides is basically that you acknowledge
the fact that it is theoretically possible for the setup to cause
temporary loss of connectivity (very minor packetloss) which may result
in DNS queries to timeout, but that the impact of such an event has
no real-life damage. 

I thought that it would be virtually impossible to get this actually
working outside of a lab-environment due to continuous route-changes on
the net. I stand corrected.

802.16 is starting to sound promising -- the first certified "WiMAX" gear is
starting to get rolled out right about now.

Still a little bit of time away for general deployment, but certainly
eliminates the wiring requirement.

When the government proves unwilling to ensure reasonable access to the
central office, why assume loosing this option benefits consumers?
Consumers will be facing either a phone monopoly or a phone/cable
duopoly.  The US lags behind many other countries in broadband access
already, where this change inhibits establishment of other carriers,
even assuming alternative last-mile technologies could prove viable in
the future.  There is now no intermediate step into this arena, unless
you consider dial-up an entry point.

Yes, it's called structural separation.


Curious what others might think about this, assuming it's not snake-oil:

Very low power and could be deployed right now in the unused adjacent-channel NTSC VHF spectrum.  VHF (and/or UHF) would seem to 
solve many of the problems with "wireless"
