Re: Very Interesting ...
Cable's capacity problem isn't their backbone connectivity. It's between the node and the headend where they've dedicated too few channels to HSI, particularly in the upstream direction. That's why they're working on SDV, DOCSIS 3, ditching analog video and other bandwidth saving measures within the local cable systems. |

Hingham, MA | There's also talk about backbone... though that seemed to be more from at&t than the cablecos. |

| Backbone connectivity savings (eg P4P and other projects) is just about saving money, not because there is an actual capacity problem.
Obviously the less data an ISP can get away with buying the better it is for them. But AT&T wouldn't be capping because of capacity...it's 'cause they're greedy scumbags following the cable whores down the price increase toilet.
In the short term cable has capacity issues within individual cable systems so in some circumstances the excess traffic is causing them capacity problems, but quickly deploying technologies like I mention above takes care of that.
Any caps are simply about increasing revenue, not because caps are necessary to maintain network stability. |

However, aren't all ISPS hooked into the backbones and simply resetting the bandwidth that level 3 providers sell? My understanding, and I might very well be wrong, is that ISPS wire neighborhoods and business. However, the actual capacity is the backbone on which the ISP leases the bandwidth. So lets say X company has a backbone in LA. This backbone has 1 10 gigabits of speed for say 100,000 people. The slow downs come w here an ISP has too many people sharing a node, but not because of said backbone. The capacity is there, just the fact an ISP doesnt have enough nodes in the area. It'd be like a 6 lane highway being able to handle those 100,000 people until construction forces it down to 2 lanes a mile before the highway ends. The highway itself is sound up until the point of exit. |

Backbone connectivity is scalable and bandwidth is cheap and evidentally getting cheaper. |

And don't forget preventing comptition from online video - after all the cable co's are terrified of becomming a "dumb pipe" provider and having their cash cow drift away like VOIP is doing to the telcos... |

Don't forget about the intermediate connections between the cable plant and the backbone peering point. Such connections need to be able to handle the traffic from every node. |

| It doesn't matter how many nodes a cable system has. Nodes themselves can handle a boatload of traffic.
The capacity crunch is solely how many channels a cable operator dedicates for traffic between that node and the headend. You can handle hundreds and hundreds of customers on a node, if you dedicate the channels to do it.
Backbone capacity is easily scaleable and because the pool of customers is so much larger, the backbone capacity isn't suceptible to overselling issues like nodal capacity is. It only takes a few seeding customers to saturate the upstream channels of a node. |

1 edit | But it is going down, in terms of the same $/Mb.
When I first got Cox in 1997 it was 3Mb for $30. Now it's 7Mb for $42.
So I was paying $10/Mb in 1997 and now I'm paying only $6/Mb. A decrease of 40%.
My 30Mb Verizon service will be less than $5/Mb, when with 768Kbps DSL many years ago I started at $50 or a whopping $65 per Mb. |

That's true. I'm watching a South Park episode via the Internet based DirecTV On Demand while I'm downloading Semi-Pro in 720P on my AppleTV. These services were once exclusive domain of cable companies. |
