Flow Control

Early request of pacing (as suggested by Bernie Brady) seems better to me 
than the current IBM proposal, especially as the IBM  proposal defines 
only solicited IPMs (i.e sent as a result of PREQ=1). With solicited 
IPMs, late pacing requests and small WAN windows you get bursty WAN data 
transfer.

It would seem to me that late requests, solicited IPMs and trying to 
anticipate buffer requirements (as per David Matusow's suggestion) would 
suffer from internal buffer management yoyoing.

I think we should define unsolicited IPMs.
