On the other hand, if you were pushing 8 and now need to push 12, you may have just bought a very expensive forklift upgrade to 40G.

Capacity/transit costs vs growth
I am looking for some rough estimates of the ratio of capacity (equipment) pricing declines versus average increase in end user capacity. For instance, say end user average capcity usage increases 50% over 3 years, would the ISP's costs also increase by 50% ? Or would increased efficency of equipment result in a 50% decrease in capacity costs yielding roughly the same total cost to the service provider ? So I am looking are some sort of ratio of gross costs increases/decreases relative to end user usage increase in usage over time. Context: Wholesale services in Canada are priced linearly and there is a process trying to convince the CRTC to review them ASAP. So if average use grows from 1mbps during peak to 1.2mbps, we are looking at 20% increase in costs in a linear pricing scheme. But if this happens over a period where there have been improvements in equipment/efficiency, then one would think the increase in costs would be less than 20%. So I am looking for any and all information that can help convince the regulator that current linear increase is not right and needs a review. any help appreciated.

Re: 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. Regards.

Re: Capacity/transit costs vs growth
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.
Re: Capacity/transit costs vs growth
If I understand your question correctly, the answer is: it depends. You can model the cost of delivering your service and keep track of three types of cost: fixed, variable and marginal. Here is a really good video that explains these: https://youtu.be/bBQVaRnHqLs You might find an industry average for certain economies of scale, but each system is so unique in it's cost structure that you have to model it from scratch. Just keep in mind that every model works with TRASH IN = TRASH OUT, so if you make the wrong assumptions, your answers won't be realistic.

There may be some accountant though who sees that unused asset and gives you a run for your money though. when you move from 1gbps to 10gbps to 40gbps links, what sort of price/gnps reduction do you get ? 20% ? 30% ?

As mentioned above, there are some points where the scale and per unit costs make more sense. I'm not familar with the model in Canada but cost models SHOULD be revisited less than 10 years apart from each other. Most people are not going to sign a 10 year deal for IP transit, and if you still want to pay 1000/Mbit please contact me, I'll setup a LLC and resell you something quickly in the US. Most 1G hardware is inexpensive these days and you can find 'cheap' 10G hardware out there as well depending on what your use case is. Real routers tend to cost real money and can even cost more to power over the lifecycle than to purchase (depending on how long you are looking at). If everyone is picking up service from Bell at Front st in Toronto, you may be able to make the case that going from Windsor to Toronto doesn't make a lot of sense and you should be able to purchase/lease your own 10 or 100G backhaul between those areas to offset cost, either with a bell provided service or by rolling your own. 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. These usually take off when the 10G costs less than 10*1G. There should be some regular open bidding that occurs as part of the CRTC model allowing for resetting the regulated rate. It's way cheaper to reach the stadium from Front st than reaching Alert, NU. 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. This is important, unless there is an incentive for people to compete in the market, you see odd things occur. I live in an ATT territory and their fiber goes within 1200 feet of my house but there are no services available. I could pay a local provider $50k to build fiber to me, but it's much cheaper to do something else (yay WISP). Unless there is some risk of business loss due to having a rate, there is no incentive for change. I await someone willing to issue a press release so Comcast or ATT will take these territories without basic broadband and announce fiber services in Michigan. - jared -- Jared Mauch | pgp key available via finger from ja...@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.

To be more accurate with this, you might want to consider what portion of every part of the overall network is attributed to the costs your customer burdens you with. This isn't necessarily easy to do, but is more accurate than thinking of only the box the customer physically connects to. You will spend differently in different parts of the network, e.g., peering, core, edge, services, e.t.c. How much of that goes back to (or is caused by) your customers? Mark.
