GrooveMan, 

Don't know that much about it but here's an attempt... 

Has to do with "traffic control" in Ethernet (I think) to prevent congestion 
on the network.  It's to prevent overloading in network nodes. 
Literally, electrical constipation. 

Back pressure signaling is used to notify a sending node to reduce its flow. 
A back pressure signal is sent 'upstream' to the first upstream node to slow 
the xmit speed to match the recieve speed of the first 'downstream' node on 
a net.  This can obviously lead to all sorts of delays on a net. 

I 'think' this is what you're asking. 

Regards, Doug
