Overview
Scheduler Policies
Virtual schedulers are created within the context of a scheduler policy that is used to define
the hierarchy and parameters for each scheduler. A scheduler is defined in the context of a
tier which is used to place the scheduler within the hierarchy. Three tiers of virtual schedulers
are supported. Root schedulers are defined without a parent scheduler meaning it is not
subject to obtaining bandwidth from a higher tier scheduler. A scheduler has the option of
enforcing a maximum rate of operation for all child queues and schedulers associated with it.
Because a scheduler is designed to arbitrate bandwidth between many inputs, a metric must
be assigned to each child queue or scheduler vying for transmit bandwidth. This metric
indicates whether the child is to be scheduled in a strict or weighted fashion and the level or
weight the child has to other children.
