Atascadero, CA | Charter Announces 60Mbps Internet Service Yeah Right...let them get their current service correct first. | |
|
 | | Fix current service first. I agree. When charter can provide pings that are acceptable to its customers and When they can provide a full 10 to 16 megs up and 1 meg down on a everyday consistant basis then im all for them increasing the download and upload speeds.
Fix whats broken and then worry about the rest. | |

Saint Louis, MO | Re: Charter Announces 60Mbps Internet Service The migration to Docsis3 should actually help with congestion. With it they can dynamically switch channels, when a given channel is overloaded. Docsis 2 cannot do this. So if you are on a particular channel(with D2) that is saturated at that particular time, you are stuck (D3 just switches channels). | |

Dynamic load balancing across downstreams is quite doable on DOCSIS 2. | |

Saint Louis, MO | Re: Charter Announces 60Mbps Internet Service If you mean dynamic like in dynamic IP then I have seen that(D2). But if you mean dynamic on a minute to minute basis(what I meant) then I have not seen that. Usually the frequency (channel) is assigned at the same time as the IP and does not change unless the connection is reset (on D2). This may be a difference between euro-docsis and us-docsis(your UK location). | |

From your link:
"You cannot select particular cable modems to be automatically moved for load balancing,"
"the dynamic load balancing method uses the Downstream Frequency Override message to move cable modems between downstream channels, which results in cable modems going offline and having to reregister, resulting in a short, temporary loss of connectivity for the customer. "
Which is essentially what I said in my previous post. | |

4 edits | Re: Charter Announces 60Mbps Internet Service Think you misunderstand.
Frequency override is for modems that are not compatible with Dynamic Channel Change, DOCSIS 1.1 modems are generally fine for seamless.
From the same link:
'DCC in DOCSIS 1.1 dynamically changes cable modem upstream or downstream channels without forcing a cable modem to go offline, and without re-registration after the change. DCC supports five different initialization metohds (0-4), instead of one, as in earlier DOCSIS support.'
You declare groups of cable modems to be automatically balanced. Bit pointless specifying a single modem.
Have another read of the link, and if you like the DOCSIS 1.1 specs, you'll find reference to DCC for both upstream and downstream there.
EDIT:
I'll finish your second quote for you:
quote:
the dynamic load balancing method uses the Downstream Frequency Override message to move cable modems between downstream channels, which results in cable modems going offline and having to reregister, resulting in a short, temporary loss of connectivity for the customer. This is because the DOCSIS 1.0 specification requires cable modems to reregister whenever the downstream is changed using the Downstream Frequency Override message.
Here's how to configure dynamic groups in IOS: »www.cisco.com/en/US/docs/cable/c···p1027265
As soon as the conditions are reached for the balancing to happen, such as a channel breaking a certain utilisation level, it happens, so it's pretty minute to minute  | |
