Some months ago, I had a look at the original catenet paper by Vint Cerf 
and compared it to RFC 791.
To my understanding, the catenet model makes stronger assumptions to the 
network segments. In particular, to my understanding in catenet, there 
was a flow control mechanism, while RFC 791 states that there is no 
mechanism for flow control.

When I rethink the discussion about congestion control during the recent 
past, I today considered, whether it could make sense to allow for a 
flow control mechanism along L 2 again.

That's a risky thought, but I dare think it ;-)
