针对在有限的通信资源保障条件下如何发挥系统的作战效能,分析基于栅格的信息分发系统的内涵实质,结合对OMG DDS规范及其实现产品RTI DDS的研究,提出基于发布/订阅的QoS策略量化计算分发业务的数据量需求的思路和方法。并将该量化结果与其它QoS策略运用到分发业务所需通信带宽的动态预测计算中,提出了相应的带宽分配权重系数计算模型和带宽预测计算方法。最后提出了一种基于预测的带宽动态分配模型。
Aiming at how to give play to the combat effectiveness of the system under the condition of limited communication resources, this paper analyzes the essence of the grid-based information distribution system. Combining the research of OMG DDS specification and its implementation product RTI DDS, this paper proposes a QoS strategy based on publish / subscribe The idea and method of quantifying the amount of data required to distribute and distribute services. Then, the quantitative results and other QoS strategies are applied to the dynamic prediction calculation of the communication bandwidth required for distributed services, and the corresponding bandwidth allocation weighting coefficient calculation model and bandwidth prediction calculation method are proposed. Finally, a predictive bandwidth dynamic allocation model is proposed.
