They would rather piggyback off of the companies that actually build networks! Hnading off at the cable pair would require the non-LEC ISP's to have DSLAMS in every central office. | |

Once they decide that faster and more reliable broadband coast to coast is in the interest of National Security then Comcast (and the others will put up or disappear. 
Remember the Defense Advanced Research Projects Agency was set up after the Soviet Union beat the U.S. into space with Sputnik. Its mission was to prevent "technological surprise."
If Uncle Sam says "give em them the best (before the Russians beat us to it again)"...
I'm kidding of course. I have Comcast. Had Verizon DSL and it sucked and cable was about the same price (cheaper with intro rate). I average 6-7 pass through and 4 while surfing with peak spikes of 15 -21. I'm not seeing a huge difference in downloading video or streaming (which could be the source servers) but over all it is faster.
Comcast should stop micro managing the bandwidth and just focus on new subscribers or they'll lose even more market share to FiOS. Ok I'm out of oxygen. | |

| Better idea, why not just bill people and provide no service but lots of promises. Basically, let's advertise say 20mbit download with burstable speeds for X amount a month. In reality, give customers a line that doesn't work and still bill them for it. Why not. Essentially, this is what Comcraptic is doing anyway. They are providing a useless line that now interferes with activities (legal and not) that the customer chooses. I guess since Comcast is now the watchdog, the *AA's should sue them when it comes to customer's usage. Since they feel the need to play police, by all means, let them take the fall when their methods still allow traffic to occur. | |

The number of unrelated events that we can relate to Comcast throttling are endless - time to get creative people! We have to make a decision, and I think this should be one of those opt-out kind of deals. On the one hand you have a vast multitude of users who have infected computers, and don't know how to control them. On the other hand you have users who may generate traffic that fits the traffic profile of an infected box, but it legitimate. For the sake of protecting the stability of the internet there should be an option to deploy this type of attack mitigation (syn rate limiting) tech to protect home users. Power users or techs should have a way to opt out and of this and simply get the dumb pipe we all have been craving for lately. | |

| how to control your network in 3 easy steps 1.invent a "bandwidth hogging" bogeyman that can be claimed to be disrupting "regular" customers and using up "scarce" bandwidth
2. put into place equipment that can see what is going across the network and "break" any attempt to use P2P applications
3. after weathering the resultant storm of publicity, quietly implement the full spectrum of "deep packet inspection" capabilities as "regular" network management.
then, just sit back and block, delay or otherwise interfere with any activity that costs the company money or keeps them from making money. | |

| 100 SYN? Nothing but bittorrent generates 100 SYN packets that quickly. So, essentially, they are just stating that if you generate 100 SYN packets WITH ANY PROTOCOL, not just Bittorrent, Comcast is sending fake TCP RSTs. So if you try and establish 100 session to a website (or 1 session to 100 different websites) they'll start throwing TCP RST flags on your sessions.
This won't be noticed by the majority of users out there, as nothing really but bittorrent attempts to open 100 sessions at once. | |
