The invention relates to the technical field of
Ethernet communication, and discloses an
Ethernet architecture, communication equipment and an auto-negotiation and link training method, the
Ethernet architecture comprises an Ethernet control module, a physical medium
adaptation layer, a switching module, and an auto-negotiation control module and a link switching module which are arranged corresponding to a channel; wherein the physical medium
adaptation layer is internally provided with at least one channel; the auto-negotiation control module is used for executing an auto-negotiation function; the link switching module is used for switching to a
data link between the corresponding channel and the auto-negotiation control module in the auto-negotiation process, and switching to a
data link between the corresponding channel and the Ethernet control module after the auto-negotiation is completed; and the switching module is respectively connected with the auto-negotiation control module and the channels, and the switching module is used for transmitting the auto-negotiation result output by the auto-negotiation control module to any channel so as to drive the channel to carry out link training. According to the invention, the problem that the channel configuration flexibility of the link in the Ethernet architecture is poor can be solved.
