This is broken by design. What would have happend if this had be done before the fiber glut in the late 90's? As far as I am aware a couple of new fiber routes have been build and a few more cities have become nodes.

I am not suggesting time machines. I am proposing that this be done now, after the fiber glut has largely been built out and when we are in a much better position to understand how the global network will evolve. That's why I suggest that the planning for the aggregation hierarchy should be done in the regions. They know more about the topology of their region and the pressures (economic, political, social) that will drive the evolution of the network in their region.

Fiber routes have very little to do with evolution of the Internet. Capacity is key, and underlying markets drive where the glass is. Internet service is bottom up. [ snip ]

Technically speaking, I don't care about where people go or where containers go. It's the fiber routes that I care about and these usually lead to interconnect points or exchanges in the major cities. I worked for GTS at the time they

All fiber must meet somewhere. It's the nature of the beast. Fiber is not dependant upon exchanges or meet me rooms, the meet-me's and exchanges are dependant upon it. -M<

were building Flag Atlantic. Even though we knew that the cables landed at Crab Meadow and Long Beach, we still referred to that end as the New York end because we were only planning to connect customers to the link in the city of New York. On a trans-oceanic hop it doesn't make a lot of difference if the traffic lands in a Sprint Pop and then has to go crosstown to MCI's PoP before being routed to its destination in Rochester. Why do the Europeans need to see the topology of New York State in order to efficiently route traffic?

So people don't build PVC's from NYC to LAX and call it one hop? -M<
