# Class CIM_PacketSchedulingService
extends CIM_ConditioningService

This class represents the scheduling service, which is a process that determines whether a queued packet should be removed from a queue and sent to an output interface. Note that output interfaces can be physical network interfaces or interfaces to components internal to systems, such as crossbars or backplanes. In either case, if multiple queues are involved, schedulers are used to provide access to the interface. Each instance of a PacketSchedulingService describes a scheduler from the perspective of the queues that the scheduler is servicing. One can describe that different schedulers support different queues, or that a scheduler supports several queues. PacketSchedulingService is modeled as a ConditioningService so that it can be aggregated into a QoSService (using the QoSConditioningSubService association) to indicate that its functionality underlies that QoS service. It participates in the NextService association to identify a subsequent ConditioningService, if any, that acts on traffic after it has been processed by the scheduler.

Name | Data Type | Default Value | Qualifiers
--- | --- | --- | ---
Name | Data Type | Value
OtherSchedulerType | string |
Description | string | This string property is used in conjunction with the SchedulerType property. When the value of SchedulerType is 1 (i.e., "Other"), then the type of scheduler to be used is defined in this attribute.
ModelCorrespondence | string | CIM_PacketSchedulingService.SchedulerType
SchedulerType | uint16 |
Description | string | This property is an enumerated 16-bit unsigned integer, and defines the type of scheduler. Values are: 1: Other 2: FIFO 3: Priority 4: Allocation 5: Bounded Priority 6: Weighted Round Robin Packet If no value is specified, 2 ("FIFO") should be assumed.
