I understand this to be geographic routing, which goes even further
than the geographic aggregation that is pretty much rejected out of
hand whenever it comes up within the IETF (which is every couple of
years or so).
Unless I'm mistaken, the idea is that geographic proximity equals
topological proximity. I'm afraid that can't work in a wired network.
If I'm in Holland I'm closer to Scotland than when I'm in Belgium. But
if I want to travel to Scotland through the channel tunnel, I need to
go through Belgium. So I need to get farther geographically to get
The way to solve this would be to lift the geo/topo alignment
requirement as soon as you reach a certain zoom level. But then
there's the traditional argument against geographic aggregation: how
do you avoid ISPs having to carry traffic for free? In other words:
who announces the aggregates to the rest of the world?
Are you familiar with Tony Hain's draft about geographic addressing?
