Abstract
Methods and system architectures are disclosed for controlling the processing of data packets in a router, which stores received data packets in one or more ingress data queues. In a first aspect of the disclosure, packets held in an ingress data queue are processed by the router at a dynamically adjusted packet flow rate. The ingress data queue has a data queue head structure, including a packets-to-be-processed field. The packets-to-be-processed field has a value indicating a selected number of packets to be processed from the ingress data queue in a given processing interval. In this manner, the packet flow rate of the ingress data queue is adjusted by varying the value of the packets-to-be-processed field, based on current operating conditions (e.g., current processor or memory utilization) of the router.
