Re: I can see both sides here...
said by djrobx  :Nope, sorry, that would be treating VOIP differently than other internet traffic, which is against net neutrality principles. Exactly. Internet network neutrality means you can't hinder nor help Internet traffic based on protocol, as to prioritize VoIP is to deprioritize other Internet traffic.
The core of the matter is this: CDV is not an Internet-based service. You cannot access the CDV infrastructure from outside of Comcast's network. |

| Exactly. If you want to identify Vonage or other traffic you have to inspect the packets. That requires DPI, which most everyone will tell you they don't want. It is either cool to look at packets or not - it can't really be both things at the same time I don't think. |

At some point, the traffic leaves the Comcast network and flows over the Internet or some TelCo's network (unless both sides of the phone call are CDV numbers). VoIP is Voice over IP and thus IS an Internet-Based service. It flows over the same Comcast LAN as other Internet Traffic until it reaches an Peering point and passes to some other ISP's network. The "Last Mile" is carried by a separate channel to the Head End but then gets commingled with all other IP traffic as it flows through the the Comcast network. |

VoIP is Voice over IP and thus IS an Internet-Based service. There is nothing Internet-based about CDV. It's using the DOCSIS network to terminate to media gateways on Comcast's network to do SS7 or private SIP/H323 handoffs. None of that traffic touches an Internet backbone.
Standard Internet VoIP can be used on any open Internet connection -- I can go to my neighbor's house with my ATA, or make SIP calls from a hotel room over the Internet. You cannot register to Comcast's SIP gateways over the public Internet. |

VoIP = Voice over Internet Protocol
Just because its using a protocol used by the Internet does not mean that it makes use of the Internet. Making use of an Internet protocol does not make it an Internet based service.
Calling it VoIP allows it to get past those +$15/month of government taxes/fees/unfees. |

They do not run 2 separate physical networks for this AND that would be the only true way to separate the traffic.
No matter how you dress up the pig, it is still a pig. The traffic flows around the world on the same pipes. At one point or another it all comes together regardless of channel, signal, or protocol. |
