Network device for transmitting packets having packet properties, including at least two input-output-buffers for queuing packets in the network device; a sojourn time calculator for calculating a sojourn related time for each head packet in the at least two input-output-buffers; a sojourn related time adaptor for, based on an adaptation function assigned to the corresponding input-output-buffer, adapting the sojourn related time into an adapted time for each head packet in the at least two input-output-buffers; and a scheduler for scheduling outgoing packets based on the adapted time.

Techniques for mitigating transmission of stale data from an implantable device are provided. In one embodiment, a method includes monitoring one or more data items stored in a data management queue prior to submission to a packet transmission queue for transmission as packets on a communication network to one or more other devices. The method also includes discarding a data item from the data management queue based on a determination that the data item has an expected arrival time to an other device that is after a latest acceptable arrival time associated with the data item. The method also includes estimating a size of the packet transmission queue, and transmitting another data item from the data management queue to the packet transmission queue based on a determination that the size of the packet transmission queue has a defined relationship to the threshold size.

The present disclosure relates to priority flow control (PFC) storm detection and processing methods. In one example method, a first network node performs PFC detection on a first port queue of a first port, and determines that a first preset condition is met. The first preset condition includes: detection is performed in N consecutive first time segments, when the detection is performed in each first time segment, a quantity of first PFC frames sent by the first port queue to a second network node is greater than a first threshold, and a quantity of one or more data packets received by the first port queue from the second network node is less than a second threshold. The first PFC frame is used to indicate the second network node to suspend sending all data flows in the first port queue, and N is a positive integer.

Provided in the present application are a packet scheduling method, a network device, a storage medium, and a computer program product. The method comprises: acquiring an allowable queuing delay of a target packet in a shaper queue; acquiring a sending countdown time of a forwarding queue, wherein the sending countdown time comprises a first sending countdown time and a second sending countdown time, the first sending countdown time corresponding to the first sub-block in the forwarding queue, and the second sending countdown time corresponding to the last sub-block in the forwarding queue; comparing the allowable queuing delay with the first sending countdown time and the second sending countdown time, so as to obtain comparison results; and scheduling the target packet according to the comparison results.
