Research on Time Advance Mechanism in RTI

RTI is the software that implements the High Level Architecture(HLA) interface specification. It provides common services to support realization of distributed simulations. Time management is an important set of service. RTI provides these services to coordinate federates’ time advance and the exchange of messages between federates. This paper analyses conservative time advance mechanism in RTI deeply. Some related issues such as LBTS computation and strategies avoiding deadlock are discussed.
