Hi Matt, Thanks for the advice. Also would like to point out that we actually cited the GeoPriv work (though -07). So it is on the list of more complete frameworks that we will look into next.

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>). - Matt Lepinski _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto
