Capacity/transit costs vs growth

Telco's cost structure model is very different from Cable Co's. Additionally the way they are regulated is also very different.

Based on the additional details you have shared, you are saying that Bell charges $1016/100meg of Colo to Colo Transport ?
Now you also need to add a bit more info, like.
    What type of transport is this ? (Layer 1).. TDM (OC3/OCX) ? SONET ? or Ethernet ?
    Is this connectivity flat rate ? or distance sensitive ?

Keep in mind that the Cost Efficiency in conjunction with Increase in Traffic is/has been only for Ethernet Transport....
not in the TDM or SONET.... 

>>> when you move from 1gbps to 10gbps to 40gbps links, what sort of price/gnps reduction do you get ? 20% ? 30% ?

While the question may be simple, the answer is more of a What if type....
When you move from 1gbps Ethernet Switches, to 10gbps Ethernet Switches you can easily spend between $5,000 to $25,000 for each Ethernet Switch.
So, if you have only 2gbps of traffic, i.e. 1gpbs infrastructure is out of capacity, you have the spend the money for 10gpbs switches, and the cost of the upgrade has to be justified via the increase in traffic of only 1gbs.

I think you should be making the case of total Revenues generated due to increase in traffic to the same location, thus the justification of the need to reduce the per 100meg rate.

I highly doubt if anyone here can give you any reasonable number on what is the cost of per 1G connection when using 10G infrastructure..simply because "10G infrastructure" has different meaning (cost wise) to different folks.

I don't doubt for a moment that you can get consensus that 10gb infrastructure can move 10gbs of traffic at a lower per unit cost, but how much lower will be a very subjective number.
