Data distribution and management

Data distribution and management (DDM) is concerned with ensuring that messages are delivered to all federates that have specified interest in the information contained in the message. The HLA currently includes mechanisms for DDM, however the services are specified independent of the time management services. This work also is examining the relationship of time management and data distribution and management services in the HLA in order to provide effective data distribution that is properly synchronized.
