Communication device, method and system for queueing packets to be transmitted

摘要

A communication device includes: first and second memories configured to store first and second packets in first and second queues, respectively; a processor configured to: select a packet to be transmitted by selecting the first packet in priority to the second packet, read the selected packet from the first or second queue, and detect the first packet stored in the first queue during reading of the second packet from the second queue; and a third memory configured to hold copied data relating to the second packet, wherein when detecting the first packet, the processor is configured to cause an internal or external part of the communication device to discard the currently read second packet, read the first packet stored in the first queue, and read the copied data from the third memory after completion of the reading of the first packet.

1. A communication device comprising:
a first memory configured to store, among packets, first packets in a first queue; a second memory configured to store, among the packets, second packets in a second queue; a processor configured to:
select a first packet to be transmitted by selecting the first packet stored in the first queue in priority to a second packet stored in the second queue,read the packets from the first or second queue, anddetect the first packet stored in the first queue during a current reading of the second packet from the second queue; and a third memory configured to hold copied data relating to the second packet, wherein
the processor is configured to calculate a ratio of a number of first packets detected in the first queue during current readings of second packets from the second queue to a total number of first packets selected in priority to the second packets, andin response to the detected first packet stored in the first queue during the current reading of the second packet from the second queue and the calculated ratio being equal to or higher than a threshold, the processor is configured to cause an internal or external part of the communication device to discard the currently read second packet, read the first packet stored in the first queue, and read the copied data from the third memory after completion of the reading of the first packet.
