Hi Fabio, all,
my thoughts on this:
1.) There are several reasons why it may make sense to have an
ALTO proxy in a home gateway or NAS, etc.
But regarding the discovery issue, how does this solve or ease our
problems? Aren't we just shifting the complexity of finding the
ISP's (upstream) ALTO server, from the ALTO client to the local ALTO
proxy?
2.) The main problems we're having with the discovery document are NOT
with the scenario "ALTO client in the resource consumer (in the home
network)". The difficult scenarios are when the ALTO client is at a
central place (e.g., bittorrent tracker, or DNS-server for
redirection in some CDN scenarios), i.e., when we have to issue ALTO
queries on behalf of a distant resource consumer. I don't see how a
ALTO home proxy could help here.
Thanks
Sebastian
