Abstract

The application provides a network communication device and a network communication method with a dynamic packet transmission ordering mechanism. The packet classification circuit sets each low-delay packet as a selected low-delay packet for storage in the corresponding selected low-delay queue circuit. The transmit ordering circuit calculates a stall time parameter for the selected low-latency packet to order with other low-latency packets to update the ordering list, wherein the stall time parameter is a ratio of a total stall time of the selected low-latency packet stored in the selected low-latency queue circuit to a dynamic service time threshold set by the corresponding selected low-latency queue circuit. The communication circuit sequentially transmits the low-delay packets according to the ordering list. The dynamic adjustment circuit calculates a difference between a total packet transmission time of the selected low-delay packet and a target delay threshold value, so as to dynamically adjust the dynamic service time threshold value according to the difference.

Description

Network communication device and method with dynamic packet transmission ordering mechanism Technical Field The present invention relates to network communication technologies, and in particular, to a network communication device and method with a dynamic packet forwarding ordering mechanism. Background A network communication device, such as an Access Point (AP) device, may transmit packets to a Station (STA) device over a wireless network at the request of the STA device. However, when the station apparatus runs different applications, different service requirements are set up, and the delay threshold values required for packet transmission by these service requirements are not the same. For example, when a station apparatus runs a video (video call) application or a real-time game (real-TIME GAMING) application with low latency requirements, low latency transmission requirements are set up, and it is desirable to receive packets as soon as possible. When the station device runs a video streaming application or a remote control application (device remote controlling) with non-low latency requirements, the non-low latency requirements are set up to receive packets within a relatively wide time frame. If the network communication device does not perform different processing on the packets with different service requirements, the network communication device often cannot meet the low-delay transmission requirements, and the station device cannot timely receive the packets of the application program corresponding to the low-delay requirements.

The transmission sequencing circuit is configured to calculate a stop-queue time parameter for the selected low-delay packet to be transmitted at each transmission time sequence, and to update the sequencing list according to the stop-queue time parameter and the sequencing of other low-delay packets, wherein the stop-queue time parameter is the proportion that the total stop-queue time of the selected low-delay packet stored in the selected low-delay queue circuit exceeds a dynamic service time threshold value set by the corresponding selected low-delay queue circuit. The communication circuit is configured to sequentially transmit the low-latency packets according to the ordered list to transmit the selected low-latency packets to the low-latency target device. The dynamic adjustment circuit is configured to accumulate a total transfer time of the selected low-delay packets from the storing to the selected low-delay queuing circuit to the transferring to the low-delay target device, and calculate a gap of a target delay threshold value required by the relatively low-delay target device of the total transfer time of the packets, so as to dynamically adjust the dynamic service time threshold value according to the gap. The invention also includes a network communication method with a dynamic packet transfer ordering mechanism, which comprises the steps of enabling a packet sorting circuit to obtain a plurality of low-delay packets with low-delay requirements from a plurality of packets to be transferred, setting each low-delay packet in the low-delay packets as a selected low-delay packet, enabling the packet sorting circuit to judge a low-delay target device corresponding to the selected low-delay packet in a plurality of target devices, storing the selected low-delay packets in a selected low-delay queue circuit set by the corresponding low-delay target device in the plurality of low-delay queue circuits, enabling the transfer ordering circuit to calculate a stop-queue time parameter for the selected low-delay packets to be transferred at each transfer time sequence, enabling the stop-queue time parameter to be the proportion of the total time of the selected low-delay packets stored in the selected low-delay queue circuit to exceed a dynamic service time threshold set by the corresponding low-delay queue circuit, enabling
