Just wanted to quickly re-iterate a point that Martin Thomson had made
during today's ALTO meeting.
GEOPRIV has been working (for well over a year) on the following problem:
"How does a device locate a server providing a given service that is
topologically close (in a network topology sense) to the device"
In the case of GEOPRIV, the service in question is a 'Location
Information Server (LIS)', but a believe that the problem of discovering
a "local" (in a network topology sense) alto server has many similar
challenges as the GEOPRIV discovery problem.
Based on my experience in GEOPRIV, I believe that getting this type of
discovery to work well in all cases is quite hard (especially if one has
security concerns regarding an attacker who may try to impersonate a
legitimate provider of the service [be it ALTO or LIS]).
Currently, the work in GEOPRIV is still incomplete, but I would
encourage anyone whose been thinking about ALTO discovery to read
draft-ietf-geopriv-lis-discovery-08, and if you have any insights on how
to improve the GEOPRIV document based on your experience with ALTO,
please send comments to the GEOPRIV list (and the authors). Also,
perhaps we can get several people who have been thinking about GEOPRIV
discovery to review the ALTO discovery documents. (I'm happy to
volunteer, though I'm definitely not as much of an expert on this topic
as Martin and James, who I have been kind enough to CC <grin>).
