| 摘要 |
The present invention discloses an Ethernet switching method, including: dividing a communication period of a transmitting component of an Ethernet port into at least two equal transmission time slots that appear regularly; deciding a transmission time slot at the Ethernet port corresponding to the Layer 2/Layer 3 (L2/L3) information of a to-be-switched Ethernet frame of fixed length; switching the to-be-switched Ethernet frame of fixed length into a time-division switch transmission queue maintained by the decided Ethernet port in the decided transmission time slot; and transmitting, by the Ethernet port in a cyclic order, to-be-switched Ethernet frames of fixed length in time-division switch transmission queues maintained in different transmission time slots separately. The present invention also discloses an Ethernet switch. The Ethernet switching scheme provided by the present invention satisfies the transmission delay requirement of time-division services transmitted at constant rate.
