The HLA Interface Specification defines services for Data Distribution Management (DDM) and Ownership Management (OM). In addition to Declaration Management, DDM is introduced to provide value based filtering on the attribute values to be communicated. The main objectives of DDM are reduction of the data to be processed by the receiving federate (scalability) and reduction of the data actually sent over the network (performance). However, applying DDM leads to an increase in computational effort by the RTI, especially when many regions need to be updated regularly. To determine the conditions, under which DDM is of benefit, a predator-prey federation has been designed and implemented. The effects of applying several strategies using DDM and OM were analyzed and experiments were conducted using the available DMSO RTI. The usage of DDM and OM is evaluated and guidelines for future use of these services are presented.
