Abstract

The present disclosure describes a method for supporting delay-limited data exchange, which is applied to a networked device including an input port and an output port, the method comprising receiving a data packet to be inserted from the input port and based on the time of the data packet to be inserted Delay restriction requires priority determination; based on the priority of the packet to be inserted, insert the packet to be inserted into the priority queue corresponding to the virtual output queue; based on the priority of multiple priority queues and the packets in the priority queue The lifetime of each virtual output queue is to select the data packet with the smallest lifetime and the highest priority as the queue to be scheduled for scheduling of each virtual output queue, where the lifetime is determined by the delay limit requirement. ; Perform matching and data exchange based on the queue to be scheduled so that the data packets in the queue to be scheduled are output from the corresponding output port. Thereby, real-time throughput can be improved and delay can be reduced.

Description

technical field [0001] The present disclosure relates to the field of data exchange, and in particular, to a method, device and medium for supporting data exchange with limited delay. Background technique [0002] With the rapid development of the Internet, more and more application fields have strict delay requirements for the transmission of data packets. Typical application scenarios may include, for example, multimedia communication systems, telemedicine, tactile Internet (Tactile Internet), industrial Internet, factory automation, and robot collaboration. These real-time application scenarios generally require data exchange to complete services with high quality. Specifically, data exchange can be achieved by building a real-time switching network with networking equipment (eg, switches) as the core of the network. [0003] Currently, some networked devices generally set priorities of queues in a virtual input queue (Virtual Output Queue, VOQ) based on QoS (Quality of...
