Re: Embracing the Distributed Model Interesting. Can you say more about the downsides of distributed architecture? Also, are cable operators at a disadvantage here because they're not alresdy IP?

Re: Embracing the Distributed Model I can't watch the video where I'm located but things like remote PHY have been espoused by other MSO's as well, I believe Jeff Finkelstein from Cox is talking about it at an upcoming LR event.  

It makes sense, as telcos have pushed DSLAMs from COs to the curb over the last decade and are using distributed DSLAM architectures.   Of course they have the obvious advantage of being all-IP already so video/DOCSIS RF combining isn't needed at the curb/node.  As MSOs move to all-IP in the future and we are left with just DOCSIS those devices may get less complicated.   

There are some downsides to distributed architectures and most PON/Active Ethernet (Google Fiber) deployments are not distributed.  You potentially put more expensive devices in the field where fewer customers are served.

Embracing the Distributed Model Shamim Akhtar has a lot to say here. If Comcast is eyying the benefits of a distributed architecture, can other MSOs be far behind? Will cable operators really forego the vcentralized headend model that they've used for so long?
