| What are they going to do to solve the bandwidth issue? From what I've seen, Comcast hasn't really started to bond more than 8 DOCSIS 3.0 channels in many areas (if they haven't started using 16+) and from what I understand, a single 305Mbps user could nearly consume everything a node has if they manage to peg their connection to the max. Whatever else would be left for scraps by normal node activity or for other network usage.
On the upstream side too, Upstream bonding is something I think they're still trying to figure out too. Doing 65Mbps on the up will most likely, once again push the node to it's limits.
Either way if Comcast pulls it off that would be interesting, but I'm betting they're going to need to clean the plants and split the nodes up a bit more, in addition to adding more downstream and upstream frequencies if they're going to pulling this sort of thing off and heavy users are going to use it.
As for FiOS, if only it would continue an aggressive build-out. With the exception of Municipal Fiber and Google's Fiber projects, FiOS is really the only thing that has legroom to handle higher speeds on GPON and XGPON Roll-outs. |

| It's possible that they are doing some >8 channel downstream bonding, but we don't notice it because there aren't any 16 channel modems available right now. If they intend on matching Verizon's 300/65, they're going to be nearly maxing out the "common" 8 down and 3 up configuration that a lot of people have. Something has to give if they're going to deploy that kind of speed on their existing system. |

| What also comes to mind is some unused channels that aren't being bonded too. My understanding of DOCSIS systems from the days of DOCSIS 1.0/1.1/2.0 is a cable company and have multiple downstream and upstream channels and they can be load balanced to prevent channel saturation. Perhaps that is what they're doing even if they aren't bonding more than 8 down, 3 up? |
