It's occured to you that FQDNs contain some structured information, no?
It has occurred to me that the name on my shirt's tag contains some structured information. That doesn't make it particularly well suited for use as a computer network routing key. Or suited at all. On Sat, Oct 6, 2012 at 2:35 PM, Barry Shein <bzs () world std com> wrote:
you can take a new idea and run with it a bit, or just resist it right from the start.
Intentionally crashing the moon into the earth is a new idea. How far should we run with it before concluding that it not only isn't a very good one, considering it hasn't taught us anything we didn't already know?
Van Jacobson had a similar observation vis a vis TCP and PPP header compression, why keep sending the same bits back and forth over a PPP link for example? Why not just an encapsulation which says "same as previous"? Now, how can that be generalized?
By observing that within a restricted subset of a problem domain there may be usable techniques that aren't portable to the broader problem domain. This is not news, and your comments have not bounded a subset of the routing problem domain in a way that would make a discussion of names as routing keys interesting.
