基于HLA的大数据量数据传输技术研究

在扩展HLA适应性的同时，需要解决在HLA系统中如何实时传输音频、视频等大数据量数据的问题，目的是为了让这些大数据量的数据通信更快、更有效，并找到合适的传输方式，可以采用的一种方法是：将一些表征性数据（如数据的大小、类型、名称等）通过RTI传输，并由RTI控制数据的公布／订购，而数据的实际内容则通过普通的网络层进行传输。实验采用TCP／IP和UDP／IP协议分别实现了这一过程，将数据传输的延时控制在100ms以下，基本上达到了预期的目标。根据实验的结果说明了上述方法是可行的，对系统性能的全面提升起到了一定的作用。

Technique for Transmitting Volume Data Based on HLA

While extend the applicability of HLA, we also have to resolve the problem of how to transmit volume data such as audio and video data in the system based on HLA, for the purpose of faster and more efficient communication, and find out the proper mode of transmission. One of the methods could be adopted is that: sending data via common network layer with token data ( such as the size, type, title of data) going over the RTI, using the RTI to control the data publishing and subscribing. The experiment implements this process with TCP/IP and UDP/IP protocol, the time delay can be controlled to less than 100ms, ultimately meet the anticipant goal for real - time transmission. According to the result of the experiment, it proves that the method above -mentioned is feasible and has some effects on the exaltation of the system performance.
