Let me make sure I understand your point here. You don't seem to be
disagreeing with the assertion that for most sites (even things like very
large universities, etc), their 'working set' (of nodes they communicate)
with will be much smaller than the network as a whole?
(This makes sense because, as the Internet has grown, the amount of
content in various languages has grown, and Spanish-speakers will only be
looking at content in Spanish, Mandarin speakers at Mandarin content, etc,
etc, naturally leading to the Internet being semi-divided into user
communities which are much smaller than the Internet as a whole. The
data-driven simulations show exactly this effect.)
So only the very largest content providers (YouTube, etc) will have
'working sets' which include a fairly large share of the entire Internet?
I have previously commented that such sites have lots of specialized
infrastructure to handle their traffic loads - do you think it will be
infeasible for them to have specialized LISP infrastructure too? (Leaving
aside for a moment what that infrastruture would look like - it's not
necessarily separate hardware, it might be integrated into existing boxes
on the periphery of their site.)
As to the cache problems, let me discuss them in a separate message (to
avoid mixing the two issues).
