A novel method of operating repeaters or other hub devices in a
local area network, such as one conforming to
Ethernet protocol, in which there are a plurality of
repeater interfaces of respectively different data rates for communicating with a link partner on a network medium. The methodology comprises determining the
data rate of operation of the link partner, and based on that
data rate, automatically steering data between the network medium and a selected one of the repeaters. In a preferred embodiment, a network
transceiver comprises one or more
physical layer devices (
PHY), and a plurality of shared data busses corresponding, respectively, to the speeds of operation of the repeaters, for interconnecting the repeaters and one or more of the
physical layer devices. A
multiplexer interconnects each of the one or more
physical layer devices to a selected one of the plurality of busses, and an auto-negotiation unit controls the
multiplexer to interconnect the physical layer devices to corresponding busses selected depending on the
operating speed of the link partner.
