Class CIM_WeightedREDDropperService
extends CIM_DropperService

This class represents a logical entity that resides in the data forwarding path of a network device. It describes the ability to drop network traffic using a Weighted Random Early Detection (WRED) algorithm. Like RED, the purpose of WRED is to avoid congestion (as opposed to managing congestion). This modification of the basic RED algorithm enables packets belonging to different traffic classes to be dropped at different queue depths. This algorithm also enables discard to be done based on different information contained in the packet header, such as IP Precedence, RSVP session parameters, or even on other factors not directly encoded in the packet header, such as the queue depth. Implementation of this class has shown that weighting should not be a property of the class (but on an association to it), and that there is insufficient data to process the drop metric. The class is deprecated pending further definition by the DMTF.

DeprecatedstringNo value
DescriptionstringThis property is an enumerated 16-bit unsigned integer, and defines the type of metric that is used to drop traffic. Values are: 1: Other 2: IP Precedence 3: DSCP Value 4: 802.1P Priority Value 5: RSVP Session 6: Queue Depth 7: Packet Arrival Rate.

OtherDropMetricstring
DeprecatedstringNo value
DescriptionstringThis string property is used in conjunction with the DropMetric property. When the value of DropMetric is 1 (i.e., "Other"), then the type of metric to be used is defined in this property.
