一种全景分析预测的数字媒体访问调度技术

A Scheduling Method of Digital Media Access Based on Panoramic Analysis and Forecasting

高效的访问调度技术是解决现代访问瓶颈的关键。传统的数字媒体访问调度方案采用单节点时间分割的方法,以单个节点为对象,无法达到全局最优的调度结果。提出一种基于全景分析预测的数字媒体访问调度技术,对所有节点的资源访问依据类型进行访问归类,在相同类中,对于不同的访问类型及进行不同加权,最后采用全景分析预测方法对整体进行调度,从而达到访问最优化。最后采用一组10节点的数字媒体进行访问调度实验测试,结果显示,采用全景预测分析方法,系统的资源访问得到极大的平滑均匀,具有很好的工程应用价值。

The high efficient access of scheduling technology was the key to solve the bottleneck of modern access. In tradi-tional digital media access control method, a single node was taken as the object and the time segmentation method was used, so the global optimal scheduling result cannot be achieved. A scheduling method of digital media access was pro-posed based on panoramic analysis and forecasting, the resource access was divided into different types, each was weighted with different value according to the actual access, then the panoramic analysis and forecasting method was used to achieve optimal access. Finally, a group of 10 nodes was used to test the scheduling result, and the result shows that with panoramic analysis and forecasting, the resource access of the system is improved smoothly and uniform greatly, it has good value for engineering application.
