5.4.6.4 QoS configuration

Mapping of priority-based QoS As shown in Figure 18 and Figure 19 the PriorityLabel from a WriterGroup , DataSetReader or PubSubConnection TransportSettings will be translated into actual values ... used on the wire. Together with the optional QosCategory the PriorityLabel will be present in the mapping table for the network interface used to transmit the data. If the combination

5.5.2.2 PriorityMappingTableType definition

array does not have any influence, as elements are indexed via the MappingUri and PriorityLabel . The combination of QosCategory and PriorityLabel are used as indices into the referenced PriorityMappingTable ... Within the PubSubConnection , each WriterGroup can contain a QosCategory and DatagramQos structure with a PriorityLabel . For the subscriber side these values are specified on the DataSetReader level. AddPriorityMappingEntry allows
