摘要： A method of configuring system layers for a synchronous Ethernet is provided. In the method, a physical layer takes charge of input and output of an Ethernet frame in direct relation to hardware, an xMII (x Media Independent Interface) layer connects the physical layer to a data link layer.

摘要： A method of enabling transmission of a time-critical control signal event in a sync frame period, such as a pause signal that is generated when the receive buffer of an Ethernet switch is filled with packets beyond a threshold due to congestion of uplink asynchronous data, is disclosed. To transmit time-critical information in a synchronous Ethernet system, a current transmission period is checked upon detection of a time-critical event. If the current transmission period is a sync frame period, time-critical control information is generated, inserted into the first sub-sync frame after the time-critical event, and transmitted. If the current transmission period is an async frame period, a control frame including the time-critical control information is generated and transmitted.
