Abstract
A communication cell scheduler and scheduling method are provided to efficiently provide periodic activities and predetermined events. A timer descriptor is enqueued to a cell scheduler timing wheel. A timer expiration for the timer descriptor is identified and an address for a DMA descriptor is fetched from the timer descriptor. Then the DMA descriptor is enqueued to a DMA engine to execute the DMA descriptor.
