Capacity/transit costs vs growth

Thu May 28 04:19:42 UTC 2015

What I am looking for is the networking equivalent to Moore's law:

"on average, every year, cost of 1gbps capacity goes down by x%"

The immediate goal is to show that rates that are fixed for 10 years are
not "just and reasonable" (text from the canadian Telecom Act) and need
a review.

In the case of Bell Canada, it carries PPPoE traffic from CO to the BRAS
location on ethernet, and from the BRAS to the aggregation point for
each ISP over L2TP (aka: IP based intranet). So the core is assume to be
modern ethernet traveling on fibre.

bell recently upgraded its BRAS from ERX 310s to ERX 320s (but claimed
to the CRTC the 320s were only capable of 1gbps capacity, on which they
were challenged as this inflated cost per gbps by a factor of roughly 80).

For cablecos, it is MPLS from the CMTS to an aggregation point.

Another aspect to demostrate is that with growing capacity purchases,
the cost per gbps should go down.
