Systems and methods for managing traffic in a network using dynamic scheduling priorities

摘要

A system for managing traffic in a communication network. The system includes a plurality of queues each configured to store data packets and a plurality of scheduling nodes each configured to process data packets from one or more of the plurality of queues. A scheduler is configured to schedule, using the plurality of scheduling nodes, respective transfers of the data packets from the plurality of queues. Each of the plurality of scheduling nodes is assigned to one or more of the plurality of queues. Each of the plurality of scheduling nodes and each of the plurality of queues is assigned a respective scheduling priority. The respective scheduling priorities are selectively changeable between a predetermined scheduling priority and a dynamic scheduling priority, wherein the dynamic scheduling priority corresponds to a priority propagated from the one or more of the plurality of queues.
