Since it is Friday, maybe some of peering experts have some time to speculate what this new approach proposed by Comcast might be, as they assert it would represent "a significant shift of Internet infrastructure."

I have no direct knowledge of the situation, but my guess: I suspect the proposal was along the lines of longest-path / best-exit routing by Level(3). In other words, if L(3) carries the traffic (most of the way) to the customer, then Comcast has no complaint--the costs can be more fairly distributed. The "modest investment" is probably in tools to evaluate traffic and routing metrics, to make this work. This isn't really *new* to the peering community, but it isn't normal either. If anybody knows for sure, I'd be interested to hear. Cheers, -Benson
