Research on Improvement of KD-RTI Communication Mechanism Base on DDS
2016
KD-RTI which is developed by National University of Defense Technology, is the run-time infrastructure of HLA simulation, and it is widely used in distributed simulation field. With the expansion of the scale of distributed simulation system, the data flow in the simulation system is more and more complex. However, KD-RTI only provides "best-effort" and "reliable" services, which cannot guarantee the quality of service of communication. To solve this problem, we use DDS as a communication method of KD-RTI. DDS is a data-centric publish-subscribe specification and it has a network controllable mechanism with lots of Quality of Service (QoS) policies. Experiments show that the improved KD-RTI perform better than the original KD-RTI in dealing with complex data streams.
