摘要
Disclosed is a hierarchy of individual schedulers with multiple scheduling lanes for scheduling items, such as, but not limited to packets or indications thereof, such that different classes of priority items can be propagated through the hierarchy of schedulers accordingly. A pipeline scheduler typically includes a root scheduler and one or more layers of schedulers with each of these layers including at least one scheduler. Each scheduler is configured to maintain items of different scheduling categories received from each of the particular scheduler's immediate children schedulers within the pipeline scheduler if any and from each immediate external source coupled to the particular scheduler if any, and to schedule the sending of the items of the different scheduling categories currently maintained to its parent schedule or external scheduler client. The items may correspond to packets, indications of packets, or any other entity.
