FIELD: radio engineering, communication.
SUBSTANCE: result is achieved by amending the destination MAC address of the received first message to be sent to the extended processor as a first destination MAC address, and then the switch circuit sending the first message to the extended processor, wherein the first destination MAC address corresponds to a service physical port of the switch circuit for receiving the first message. The extended processor can resolve the first destination MAC address to determine that the first message is from the service physical port.
EFFECT: shorter time for processing protocol messages by using an extended processor scheme.
