@Alan

Cable cos don’t have the same physical plant model as old-school telco, but they still have COs. The is where the video headend is. It is also the aggregator point to connect the distribution nodes to the national backbone. As you say, distance between the user and CO is unimportant due to the active node topology. It is distance to the node that matters for potential throughput. The issue I was bringing up about Cable COs is that they are not standardized even within the same market. And as far as reliability is concerned, that tends to be more of an access to backbone (through the CO) issue than an RF performance (the DOCSIS link from the node) issue.

I thought cable provider plants did not use the CO model, but a digital carrier over RF that mimics a metropolitan Ethernet WAN. In these cases, distance is less of an issue, or a non-issue, unlike DSL of TP.

@John

No. Reliability varies from market to market anyway, as much of Comcast’s network was built from a conglomeration of small regional operators. There is no standardization for the central offices. Things are even worse in metro-areas, which are cobbled together from what used to many geographically smaller markets. Moving 10mi can put you on a different CO with different reliability and even different network performance (uplink throughput limits seem to range quite widely). There is little chance that cable cos will do any sort of major overhaul that brings uniformity to the national network any time soon. Maybe when FiOS is available to over 50% of the country . . .

Does DOCSIS offer any advantages in terms of reliability/uptime? I’m happy with the speeds I get from Comcast right now but the connection goes down once a week here in seattle. A nuisance to say the least.

Yes, it is faster to the cap, but remember that if the average usage gets close to the cap then comcast will rethink it. So get your HD downloads ready. http://gigaom.com/2008/09/24/two-ways-to-get-comcast-to-ditch-the-data-cap/

Can someone share their insights on what wider deployment of DOCSIS 3.0 should/could mean for cable’s long expected assault on the small business voice services market? With telcos all but conceding that DSL can’t compete with cable’s fatter pipe what will happen in the business market?

Previous commenters are right (and faster than me). Nice bandwidth / tolerable pricepoint, but just amplifies the bandwidth cap issue.

GigaOM: I would really like to read a piece on how the broadband infrastructure is build in different countries. Being able to charge prices like Comcast would make broadband providers in some countries insanly rich. And in others I guess it would create a loss. If we put poor countries aside, how come the cost of providing broadband is so different?
