Hi folks,
I found a new version of draft-penno-alto-protocol
(draft-penno-alto-protocol-03.txt) and I have a question about it.
Since an ALTO Server presents to ALTO clients its "my--Internet View",
it may be reasonable for this view to be accurate in describing "near"
Network Locations and being less and less accurate when we move away
from them. So my question is: is there a way to represent "the rest of
the world"?
It seems, reading section 6.3.2.2, that every endpoint is mapped to a
PID (since there's nothing like a 404 "No PID for the endpoint" response
available), so we may group all the "far" networks we have few
information about ("the rest of the world") within a PID. The problem
with this approach would be how to answer to a Reverse PID Property
Lookup on such a PID (enumerating all network maps of far networks?).
Have you already addressed this issue?
Regards,
Antonio Fusco
PS: I found in appendix C.2 a Reverse PID Property Lookup response with
three PID, the third one mapped on a 0.0.0.0/0 mask: is it intended to
represent "the rest of the world" (and so PIDs in the response have to
be processed sequentially)?
