I'd have to see the Ericsson work.  And I'm not an expert in self-similarity
though I try to keep up with the papers.  That said, the work I've seen
to date on self-similarity has nothing to do with congestion.

It often does have to do with traffic interacting with other traffic.
But the queues don't have to be full, or even near full, for interactions
to occur.
