return to the Quality of Service (QoS) Parameters

The OWNERSHIP_STRENGTH QoS policy should be used in combination with the OWNERSHIP policy. It only applies to the situation case where OWNERSHIP kind is set to EXCLUSIVE.

The value of the OWNERSHIP_STRENGTH is used to determine the ownership of a data-instance (identified by the key). The arbitration is performed by the DataReader. The rules used to perform the arbitration are described in the Data Distribution Service (DDS) SPEC under EXCLUSIVE kind.
