Data Distribution Management

Azzedine Boukerche and Yunfeng Gu


In general, DDM (data distribution management) deals with two basic problems: how to distribute data generated at the application layer among underlying nodes in the distributed system and how to retrieve data whenever it is necessary. Alternatively, these two problems can also be described as partitioning of the application data space and mapping from the application data space into the system identifier space. The concept of DDM can also be found in HLA/RTI (high-level architecture/run-time infrastructure) under IEEE Standard 1516. It is one of seven service APIs provided by RTI. HLA is a general-purpose architecture for real-time distributed interactive simulation systems. It is used to support the portability and interoperability of a large number of distributed simulations across various computing platforms. RTI ...
