Abstract: A method of Ethernet switching, including: dividing the communication time of output section of every Ethernet port into at least 2 same size time slots, determining the output time slot of the Ethernet port which corresponding to the L2/L3 information of the fixed size Ethernet frame to be exchanged, exchanging said fixed size Ethernet frame to the time-division switching output queue maintained by the determined time slot of the Ethernet port, cyclically outputting said Ethernet frame of the time-division switching output queue maintained by the every time slot via the Ethernet port. An Ethernet switching device is also provided and thus can meet the requirement of transmission delay of same velocity ratio time-division service transmission.

Abstract: A method for synchronous time division switch is provided by the present invent, and the said method includes the following steps: with the transmission time of single byte as an unit, the time for receiving and transmitting each Ethernet frame of fixed length in the Ethernet port is divided respectively to input slots and output slots, and the input slots and output slots are numbered respectively in turn; the data is received circularly according to the number of input slots through the Ethernet port; the data received in each input slot is interchanged to the corresponding output slot; according to the number of output slots, the data is transmitted circularly through the Ethernet port. An equipment for synchronous time division switch and two kinds of equipment for the Ethernet switch are also provided by the present invent. By using the method for synchronous time division switch in the present invent and making synchronous time division switch in the Ethernet, the cost of synchronous time division switch will be depressed.
