  I should have been a bit more accurate here.  The proposal for
pushback is actually earlier than the implementation paper I cited above:

  "Controlling High Bandwidth Aggregates in the Network.  Ratul Mahajan,
   Steven M. Bellovin, Sally Floyd, John Ioannidis, Vern Paxson, and Scott
   Shenker.  July, 2001."

and it also included an internet-draft:

I believe that Steve Bellovin gave a talk about it at NANOG 21:
