带有QoS的分布式仿真通信机制研究

QoS和分布式虚拟仿真都是近年来研究的热点,分布式虚拟仿真系统中对于通信机制的QoS 要求很大程度上决定了仿真系统的准确性和实时性.以一个飞机仿真训练系统为基础,重点讨论了分布式仿真系统中的通信机制及对通信的QoS请求,建立了基于内容的区分队列模型,模型采用CBWFQ基础上的LLQ队列调度算法来满足IP请求的QoS,提高了分布式仿真的实时性和准确性,并通过试验分析验证了模型的可用性.

Research on Distributional Simulation Communication with QoS

QoS and the distributional hypothesized simulation are the hot spots which the recent years studied, in the distributional hypothesized simulation system has decided simulation system's accuracy and timeliness to a great extent regarding the correspondence mechanism's QoS request. This article take an airplane simulation training system as a foundation, discussed in the distributional simulation system's correspondence mechanism with emphasis and requested to correspondence QoS, established based on the content discrimination formation model, the model has used CBWFQ in the foundation the LLQ formation dispatch algorithm to satisfy IP request QoS, enhanced the distributional simulation timeliness and the accuracy, and has confirmed the model usability through the actual effect.
