Class CIM_WRRSchedulingElement


  extends CIM_SchedulingElement
This class is a subclass of the abstract class SchedulingElement. It introduces a new property, WeightingFactor, to give some inputs a higher probability of being serviced than other inputs. It also introduces a Priority property, to serve as a tiebreaker to be used when inputs have equal weighting factors. As is the case with all subclasses of SchedulingElement, the input associated with an instance of WRRSchedulingElement is of one of two types: either a queue, or another scheduler. Because scheduling of this type is always work conserving, the inherited boolean property, WorkConserving, is restricted to TRUE in this class.

Captionstring
DescriptionstringThe Caption property is a short textual description (one- line string) of the object.None TRANSLATABLE= true
MaxLenuint3264None None
Descriptionstring
DescriptionstringThe Description property provides a textual description of the object.None TRANSLATABLE= true
ElementNamestring
DescriptionstringA user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information. Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties. Note that if there is an associated instance of CIM_EnabledLogicalElementCapabilities, restrictions on this properties may exist as defined in ElementNameMask and MaxElementNameLen properties defined in that class.None TRANSLATABLE= true
InstanceIDstring
DescriptionstringWithin the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. In order to ensure uniqueness within the NameSpace, the value of InstanceID SHOULD be constructed using the following 'preferred' algorithm: <OrgID>:<LocalID> Where <OrgID> and <LocalID> are separated by a colon ':', and where <OrgID> MUST include a copyrighted, trademarked or otherwise unique name that is owned by the business entity creating/defining the InstanceID, or is a registered ID that is assigned to the business entity by a recognized global authority. (This is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness <OrgID> MUST NOT contain a colon (':'). When using this algorithm, the first colon to appear in InstanceID MUST appear between <OrgID> and <LocalID>. <LocalID> is chosen by the business entity and SHOULD not be re-used to identify different underlying (real-world) elements. If the above 'preferred' algorithm is not used, the defining entity MUST assure that the resultant InstanceID is not re-used across any InstanceIDs produced by this or other providers for this instance's NameSpace. For DMTF defined instances, the 'preferred' algorithm MUST be used with the <OrgID> set to 'CIM'.None TRANSLATABLE= true

Priorityuint16
DescriptionstringA 16-bit bit unsigned integer which serves as a tiebreaker, in the event that two or more inputs have equal weights. A larger value represents a higher priority. While this condition may not occur in some implementations of a weighted round robin scheduler, many implementations require a priority to resolve an equal-weight condition. In the instances where this behavior is not necessary or is undesirable, the property may be left unspecified. If this property is specified for any of the WRRSchedulingElements associated with a PacketSchedulingService, then it MUST be specified for all WRRSchedulingElements for that PacketSchedulingService, and the property values for these WRRSchedulingElements MUST all be different.None TRANSLATABLE= true
WeightingFactoruint32
DescriptionstringA 32-bit bit unsigned integer defining the weighting factor that offers some inputs a higher probability of being serviced than other inputs. The property's minimum value is 0, its maximum value is 100000, and its Units are thousandths.None TRANSLATABLE= true

WorkConservingboolean
DescriptionstringA boolean property indicating whether the PacketSchedulingService tied to this instance (by the ElementInSchedulingService aggregation) is treating the queue/input tied to this instance, in a work-conserving manner. The queue/input is indicated by either the QueueToSchedule or SchedulingServiceToSchedule association. Note that this property is writeable, indicating that an administrator can change the behavior of the SchedulingElement - but only for those elements that can operate in a non-work conserving mode.None TRANSLATABLE= true
