ABSTRACT:
A deficit round-robin scheduler including a round-robin table configured to store a plurality of cycle link lists, wherein each cycle link list includes a head flow identification (FLID) value identifying a first flow of the cycle link list, and a tail FLID value identifying a last flow of the cycle link list. A flow table is provided having a plurality of flow table entries, wherein each of the flow table entries is associated with a corresponding flow, and therefore has a corresponding FLID value. A packet queue is associated with each flow table entry, wherein each packet queue is capable of storing a plurality of packets. The deficit round-robin scheduler also included an idle cycle register having an idle cycle entry corresponding with each of the cycle link lists, wherein each idle cycle entry identifies the corresponding cycle link list as active or idle.
