I doubt that "one ALTO PID := one AS number" is a reasonable scheme for an ALTO server providing a global view on the internet. On the one hand, the number of AS is quite high, on the other hand, there are major carriers that have their residential DSL, 3G wireless, corporate customers, and data centers in the same AS. Maybe something like "100 geograpic locations on the world" X "10 classes of access link" = 1000 PIDs would be more realistic? Not sure. Anyone planning to deploy an Internet-wide ALTO service who wants to share her or his plans wrt. network map layout with us? > And what seems realistic now may not be realistic 10 years from now.

I am tempted to say that in 10 years, downloading a 130 MB file every some seconds will probably not be considered a significant burden or waste of ressources, at least for a large P2P tracker, CDN control node, etc. :) Thanks Sebastian _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto
