TRAFFIC SCHEDULING DEVICE

摘要

The disclosure relates to a traffic scheduling device for scheduling a transmission sequence of data packets, stored in a plurality of traffic flow queues, an eligibility state of each of the traffic flow queues for the scheduling is being maintained in a hierarchical scheduling database describing a relationship among the plurality of traffic flow queues. The traffic scheduling device includes: a plurality of interconnected memory cluster units. Each memory cluster unit is associated to a single or more levels of the hierarchical scheduling database and each memory cluster unit is coupled to at least one co-processors. At least one co-processor is software-programmable to implement a scheduling algorithm. The traffic scheduling device also includes an interface to the plurality of traffic flow queues.
