Stephen F Dreyer, Eric T West, Donald W Alderrou: Automatic MAC control frame generating apparatus for LAN flow control. LSI Logic Corporation, D Alessandro & Richie, August 1, 2000: US06098103 (34 worldwide citation)

Pre-formatted MAC Control PAUSE frames are generated by a MAC device rather than by a switch. These may be automatically generated and transmitted upon the occurrence of a full or near full condition in the input buffer of the MAC device. The MAC device, upon receipt of a MAC Control PAUSE frame, al ...
