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.<h3> Table of Contents<br> <a href="#c_hierarchy">Hierarchy</a> <br> <a href="#c_subclasses">Direct Known Subclasses</a> <br> <a href="#c_qualifiers">Class Qualifiers</a> <br> <a href="#c_properties">Class Properties</a> <br> <a href="#c_methods">Class Methods</a> <br> </h3> <hr> </hr> <H2> <a name="c_hierarchy">Class Hierarchy</a> </H2> <a href="CIM_ManagedElement.html">CIM_ManagedElement</a> <br data="@NAME"> |<br> +--<a href="CIM_SchedulingElement.html">CIM_SchedulingElement</a> <br data="@NAME"> |<br> +--<b>CIM_WRRSchedulingElement</b> <br data="CIM_WRRSchedulingElement -- CIM_SchedulingElement"> <H2> <a name="c_subclasses">Direct Known Subclasses</a> </H2> <H2> <a name="c_qualifiers">Class Qualifiers</a> </H2> <TABLE BORDER="1" CELLPADDING="1" WIDTH="100%"> <TR> <TH>Name</TH><TH>Data Type</TH><TH>Value</TH> </TR> <TR> <TD VALIGN="TOP">Description</TD><TD VALIGN="TOP">string</TD><TD VALIGN="TOP">This class is a subclass of the abstract class SchedulingElement.

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.</TD> </TR> <TR> <TH ROWSPAN="5" VALIGN="TOP">WeightingFactor</TH><TD ROWSPAN="5" VALIGN="TOP">uint32</TD><TD ROWSPAN="5" VALIGN="TOP"></TD> </TR> <TR> <TD VALIGN="TOP">Description</TD><TD VALIGN="TOP">string</TD><TD VALIGN="TOP">A 32-bit bit unsigned integer defining the weighting factor that offers some inputs a higher probability of being serviced than other inputs.
