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. The data link layer has a sync frame processor for processing a synchronous frame and an async frame processor for processing an asynchronous frame. A parser and multiplexer (MUX), included in the x MII layer, construct a super frame with a synchronous frame and an asynchronous frame, transmit the super frame through the physical layer, parse a received super frame into a synchronous frame and an asynchronous frame, and transmit the synchronous and asynchronous frames to the 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.

摘要： Disclosed is a method for establishing a synchronization in a synchronous Ethernet system. Devices are classified according to the type of the devices, and a device having a highest class in the synchronous Ethernet system is detected, then it is determined if the device having the highest class is able to serve as the timing master. If so, the device having the highest class is able to serve as the timing master if only one such device is detected; otherwise, the timing master between devices having the highest class is selected through a collision algorithm.
