Abstract:
1. A method for communication, the method comprising: in an Ethernet network comprising multi-rate link partners coupled via an Ethernet link: notifying, by a first of said multi-rate link partners, a second of said multi-rate link partners of a change of data rate in both directions on said Ethernet link; and configuring said first of said multi-rate link partners to implement said change of data rate for communication of data from said first multi-rate link partner to said second of said multi-rate link partners by controlling one or both of pulse amplitude modulation levels and signal constellation, wherein said implemented change occurs independently of delays that occur when, as a result of said notification, said second of said multi-rate link partners implements said change of data rate for communication of data from said second of said multi-rate link partners to said first of said multi-rate link partners; wherein said notification comprises a bit pre-pended to each of a plurality of Ethernet frames.
