The Research and Implementation of a General HLA Data Collection and Playback Application

摘要

As the far-ranging use of High Level Architecture (HLA) federations increases, the demand for tools that support operating in this distributed environment continues to grow. One important capability is the ability to collect and playback the data exchanged during an execution. Our aim is a general HLA federation runtime tool for the collection/playback and analysis of any federation execution data, so that tools to support HLA federations do not be limited and tied to a particular set of simulations. This paper discusses the demands, the technical challenges involved with developing a federation-independent data collection and playback system, and some important issues a federation developer must be aware of. In this paper our solution is put forward, which consists of three pivotal technical issues: the architecture of the data collection/playback tool, the object-serialized writing and reading technology of the execution data, and the architecture of HLA simulation results database.
