I see that close to 30% utilisation across some (others have close to 10%)
of my DSL links is just Internet background radiation.

And it seems the bigger the link, the larger the amount of radiation
received.

You also seem to be assuming that everything is initiating things on their
links all the time. Guess what. Speaking from a domestic setting - I have no
control over what time of day my Wii decides to downloads new upgrades /
news items etc.

I assume things will be even less predictable when TV providers decide to
'pre-stream' shows to a bunch of households as well.
