RE: Query re request routing

["Reinaldo Penno" <rpenno@nortelnetworks.com>]

Hi Phil,

I disagree that the first hop will always the owned by the ACN. The first
hop might be within the ACN premisses, but not owned but the ACN. Or the
first hop might not even be within the ACN premisses. I have seen examples
where the ISP forbids the ACN do perform caching on their content by
contract. The first hop in this example must be a cache within the ISP
premises.

In other words, in a brodband access network if you are a subscriber of ISP
A, you will redirected to ISP A surrogates, midia caches and application
server sitting or not within the ACN premises or to a set of caches owned by
the ACN and shared by all ISPs and ASPs.

regards,

Reinaldo

In summary, the ACN is doing some form of "edge caching" for their user
base today, and they're going to keep doing it. Since that "first content
hop" is always going to be owned by that ACN, that will always be a
potential bottleneck to the user experience (though it won't be if the ACN
does their job). So the publisher might as well accept that fact and
leverage the fact that it's there (make the most out of it: leverage it for
distribution, milk it for accounting data).
