Hi Sebastian, By peer-to-peer software entities what do you mean exactly, the client or the service?
Even if the ALTO service uses ASNs, it could still use client IPs do its own mapping to ASNs. Or a tracker could provide HLA (ASNs) for the peer list if the ALTO service used by a client needs that as input. I think there are papers that use ASN base locality. Thanks Saumitra -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Sebastian Kiesel Sent: Monday, April 20, 2009 8:03 AM To: [email protected] Subject: [alto] ALTO client protocol and Autonomous System Numbers Hi, in the ALTO client protocol, host location attributes are used to describe the location of one or a group of hosts in the network topology, for which ALTO guidance is requested or expressed. Several solution proposals say that in addition to the obvious approach of using IP addresses or IP prefixes, one could also use Autonomous System Numbers (ASNs) as host location attributes. I am wondering whether this is more a hypothetical idea, or whether this has actually been tested, e.g., in one of the field trials? What is the advantage of conveying ASNs to the peer-to-peer software entities, which probably don't have a module for mappings from IP addresses to ASNs, as this was generally not needed so far? thanks, Sebastian -- Sebastian Kiesel mailto:[email protected] Network Research Division tel:+49-6221-4342-232 fax:+49-6221-4342-155 NEC Laboratories Europe Kurfuerstenanlage 36, 69115 Heidelberg, Germany -- NEC Europe Limited Registered in England 2832014 Registered Office NEC House, 1 Victoria Road, London W3 6BL _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto
