Re: Legal P2P will be fostered; illegal P2P will be punished
said by swhx7  :Why would they ever invest in network capacity? The only time that happens is when there's competition in the local broadband market. And if there is one other provider, they'll invest just enough to equal or slightly exceed its offering, and not a cent more. If you look at their qtrly and annual reports you would see they invest on average $1 billion a year in infrastructure. So all these claims that Comcast never invests are pure nonsense.

| Those numbers include building out to new markets and maintaining existing infrastructure. How much of it is for increasing capacity? It doesn't make sense for any big ISP to improve the "last mile" (where all of the notorious congestion is) unless a competitor is drawing away customers. |

Alexandria, VA | It seems to me that all of the well known ISPs are routinely announcing "last mile" improvements. Comcast is bringing DOCSIS 3, AT&T continues to extend fiber and deploy VDSL, Verizon continues the FiOS rollout, etc. What am I missing? |

So all these claims that Comcast never invests are pure nonsense. I think Comcast invested $6 Bn but that's not quite the $10 Bn Verizon put into theirs nor the $17 Bn borne by AT&T.
Still, I want to know the configuration of a "Burst" node. What are the sizes of the bandwidth pools being divided by how many homes? This will tell me whether they're doing meaningful upgrades or just pushing out modem configs at a whim.

To a special 1% of their customers who are rich and live in ideallic suburbs. FiOS is only available to 28% of Verizon landline customers as of 2007 Q4.
Comcast won't deploy DOCSIS 3 unless there is Uverse/FiOS competition in the market. |

Speaking of node architecture. Its interesting most CMTSes are built around a shared design of the downstream link, 4 nodes use an identical downstream channel, but each node has a different upstream. The CMTS has 4 upstream ports, and 1 downstream. So the upload may pass 100 houses, while the downstream passes 400. I'm not sure if this is just 1990s thinking or downstreams are really never used and its always upload that is maxed out. |

said by patcat88 :FiOS is only available to 28% of Verizon landline customers as of 2007 Q4. Wow, only 28% in 2007 Q4? Considering the VZ only started deploying FiOS in 2004, I'd suggest that upgrading 1/4 of their "last mile" infrastructure in merely three years is extremely good.said by patcat88 :Comcast won't deploy DOCSIS 3 unless there is Uverse/FiOS competition in the market. What? What about the St Paul/Minneapolis deployment? What competition is there? Also, what about Comcast's announcement to deploy DOCSIS 3 to 100% of their footprint by mid-2010? |
