Disquisition to general purpose HLA data playback

For supplying the capability of replaying the HLA federation execution data and solving the issues demanded by playback that data must be integrated as a whole, time order must be exactly, run efficiency should be highly and the solution should be general-purpose, this paper explores the issues of data replaying in HLA federation, analyzes the requirements and the impacts of HLA on playback, points out that the essentially general purpose is a concept of federation independent, and excogitates a data processing method to deal with the replayed data by means of object. Relying on the strategy of a concentrated playback federate, the playback solution was putted forward, which is based on the technology of data's object serializing and federates' automatic-generating. The solution realizes the goal to make a general purpose data playback. In the end, this paper introduces the application of the general-purpose playback tool.
