ABSTRACT:
Devices and methods are provided for enabling high-speed data communication at relatively low cost. Some methods allow devices to communicate by selecting a data transfer rate from among multiple data transfer rates. Some such methods allow devices to communicate according to the highest data transfer rate among multiple data transfer rates at which communications can be made without exceeding a predetermined error rate. Communications may be enabled between a first device operating at a relatively higher data transfer rate and a second device operating at a relatively lower data transfer rate. Pause frames or the like may be used to rate limit data received from the first device and maintain an average data transfer rate for communications with the second device at the lower data transfer rate.
