Class CIM_PrecedenceService
extends CIM_QoSService

This class represents a specialization of the general concept of forwarding network traffic by adding specific semantics that define how traffic is forwarded based on the value of the ToS byte of a packet. This class is used to enable DiffServ devices and non- DiffServ devices to exchange traffic. This is done by defining a sibling class, DiffServService, to represent devices that forward traffic based on the DiffServ code point. This enables the administrator to define mappings between devices that do not support DiffServ (and instead use IP Precedence) and those that do support DiffServ. PrecedenceService is deprecated since forwarding based on the value of the ToS byte is specified using a FilterList, which is associated with a ClassifierElement. If there is a need to distinguish a higher-level set of coordinated QoS services, the QoSService class can be instantiated directly.
