CIR?

You assume things not in fact, primarily that I have the money to increase capacity. Burstable costs more than full rate. One can use 3 lower end routers to adequately handle 3 OC3 circuts much more cost effectively than buying a single high end router to handle OC-12, gig-e, etc. In addition, if the circuits are handled off at different geographic locations, you will need 3 high end routers to handle the OC-12, gig-e, etc, which increases the price exponentially.

You also assumed that OC-12 and Gig-e is available in the geographic region and that the interconnected networks can support such throughput in that portion of their network.

I dont know which world do you live in, but today the sales people will beg
for 100Mbit/sec CIRs on OC-12 links just to meet the quotas. So, why dont
you get those 100Mbit/sec CIRs on OC-12c?

I live in rural America. I provide access for rural America. There is only one public exchange point close buy and it is over 100 miles from my nearest pop (and the exchange has it's own problems). Capacity from various networks is limited, and it can take over 6 months to get the carriers upgraded to handle a new OC3, much less OC-12 or gig-e.

Why is your 100Mbit/sec delivered over OC-3s when with 100Mbit/sec CIRs you
can get OC-12 ports from basically everyone?

Your perspective is skewed. OC-12 ports are not available from everyone, everywhere. Obtaining, lighting, and maintaining fiber for long haul is not inexpensive.

Network planning *is* about not making mistakes.

Only in an ideal senario. Cost has a lot to do with it. I've watched numerous companies enter Chapter 11 due to spending too much in capacity. The perfect network is not the perfect business model.

Performance does not depend on cost effective interconnects. They are NOT
related.
No, but if you do not have cost effective interconnects, you will not have a business. Operating at a guaranteed loss is stupid at best.

Rubbish again. The fundamental problem with this entire industry is that
some very clever marketing and sales people managed to convince entire bunch
of rather bright geeks that networks are complicated. The truth is, it is
not, however, since you have been told that it is over a million times, you
want to believe that it is.

To use your word, "Rubbish." Your opinions are based upon specific business models and available resources. It does not take into account that costs do limit available resources. In many cases, money itself is the resource that is lacking. Marketing and sales people do not hold sway over everyone, but many of those people are also shrewed in business and recognize that concessions must be made to maintain profitability.
