is there a clear understanding of "the edge" in the network operations community? in a simpler world, it was not that difficult, but interconnect has blossomed and grown all sorts of noodly appendages/extentions. I fear that edge does not mean what you think it means anymore.
For 5 9's worth of eyeball networks hanging off consumer-grade ADSL and cable connections, it's still the edge and still trivially filterable. If that's a problem, the ISP can upsell a business-class connection that doesn't filter. ;)
5 9s? I'll go w/ big, but this seems a stretch to me. if true (it might be), then filtering ought be done and catch the delta. I still posit a baseline that does not fit this lowhanging fruit... (trill networks, L2 transparent bridging, L2-L3-VPNs, etc.) /bill
