Re: A word on QOS and prioritization said by NetAdmin1:Part of the problem is that Comcast and others have been pulled into the battle of the cablecos versus the telcos, resulting in insane speeds for ridiculously low prices. I don't know where you get the idea that our speed is particularly fast or that our prices are low. Compared to the rest of the high-tech world, we're not doing so hot -- even though we invented this Internet thing.
That said, Comcast has been offering 6 Mbps since mid 2005. Moore's Law and Cisco's worldwide bandwidth trends both say that our speed should have doubled about every two years. It's now mid 2008 and we're looking at 6 months to a year before Comcast's next speed upgrade.
They've fallen behind.

1 edit | I do understand it, but you are correct that what I described isn't Moore's law per se, but an extrapolation...
For example, I cite the mighty uncitable Wikipedia: http://en.wikipedia.org/wiki/Moore%27s_law#Other_formulations_and_similar_laws |

| Okay, I see where you got that from now...
While you are right that speeds should double every year based on that statement, the reality is that it doesn't hold true at the edge of the network. The applications of "Butter's Law" only really makes sense for backbone circuits. Look at ethernet for an example - it took several years for ethernet to progress from 10Mbps to 100Mbps to 1Gbps to 10Gbps. The progression from 10Gbps to 100Gbps is proving to be even slower.
While optical fiber capacities do increase at an impressive pace due to tricks like DWDM, the costs of pushing those advances to the edge of the network are problematic. That doesn't mean I don't think FTTH should be in wide deployment now, but there are other problems. Equipment is not nearly as easy to swap out in the last mile to keep up with the newest advances. And with most providers being traded on the public market, most investors (wrongfully) don't like CAPEX because it has the effect of lower short term gains.
I understand now what you are saying and in an ideal world, the network would be that flexible. Sadly, short sighted investor mentality and the idea that you only need just enough to keep up with the competition is a mainstay of the American way of doing business.

Instead of quarterly reports, can we ask the regulators to roll the dice and make reports on an irregular interval with an average of 5 reports every 3 years?
The current regime of trying to make expectations each quarter really threatens any long-term vision.
