Analysis of HLA/RTI Data Management Method

Distributed interactive simulation has become the direction of the simulation technology development.Future distributed interactive simulation will be built on the internet,so to reduce the load of network has become an important issue.High Level Architecture(HLA),which is proposed by Department of Defense(DoD) of America and is a new architecture for distributed simulation,has found more wide application in military simulation.It aims to deal with mutual operation between different simulation systems and reuse.HLA provides services of declaration management and data distributed management to distribute data in order to limit the messages received by federates to those of interest.The article compares the difference in the method of data management between HLA and DIS and briefly states the characteristic and localization of DIS,and then analyzes the basic principles of HLA/RTI declaration management and data distribution management.
