My bet is that in cable nets, Internet usage is highest before prime

effective use of overall net capacity, where the full net capacity
can be applied at all times, to whatever service people want to use
then.
You would lose that bet. Both are highest during prime time.
As always, best to check your facts, Craig. Before arguing.

This claims that Internet rush hour is 7-9 PM, in the UK anyway. TV prime time
goes to 11 PM, does it not? My sister used to use 3G for broadband. She got
reduced rates after 5:00 PM, presumably because 3G is used more during the day
than at night. Wired Internet usage ain't going to be all that different.
An all IP net would only be more efficient if EVERYONE wanted to
watch on-demand services.
Do you really think that Internet streaming only works for on demand? You'd be
wrong, and we've covered this a lot of times already. Internet streaming is
also more efficient for live/linear viewing, because it only clutters up those
PONs that have "group members" in such IP multicasts. Otherwise, the multicast
takes up no last mile bandwidth. Unlike the case of your legacy broadcast
streams, which are always there regardless of usage.
The reality is that much more than half are watching the linear
networks, when DVR time shifting is taken into account.
Sorry Craig. Since less than half of people watch linear/live, an all-IP
infrastructure is even more desirable. Having to dedicate 80% or more of your
cable capacity, just because maybe a tiny fraction of that is being used by
DVRs for time-shift viewing, is silly. Much better to let the traffic go only
where it's actually being used.
