What is the ideal way to aggregate the 40 10G connections from the uplinks of the chassis? I would guess a 10G switch since 10G ports on a router would be much more expensive? Definitely aggregate into a switch first unless you want to run a Layer 3 switch as your router, which I don't recommend.

Scott, Thanks for the long post. We will use a layer 2 10G aggregation switch then to aggregate the chassis at the core location. Do you have any recommendations on 10G switches? Yes I realize the math is a little backwards as this is all hypothetical at this point. We would provision each ONT

Roland, I agree with everything you mentioned in your email. No matter how much money and resources you have, if you don't have the talent and people required to get the job done the project will fail. There a many outfits, like Scotts for example, that will handle most all of these issues for an

I have read both the Juniper MX and Cisco ASR9K do support this advanced BRAS functionality, what Juniper calls Subscriber Feature Management and what Cisco calls BGN. These software functions run on the router itself, however the are not free or included with the base chassis. To enable these you

Scott, Thank you for your input. What do you recommend for network segmentation? A VLAN per Chassis, a VLAN per service, or a VLAN per customer/port? When you say qinq VLANs are you referring to the CVLAN model? I am really interested to know how the largest providers, like Comcast, ATT, and
