对数字化信息服务云平台的资源准确置换可以提高云平台的数据预取和资源调度能力.传统方法中对信息服务云平台的资源置换采用边缘逆理论并行查询置换算法,不能满足多媒体数据传输的QoS需求.提出一种基于QoS维度分箱的数字化信息服务云平台资源置换算法,以全局度量为中心节点,进行溯源处理,采用QoS维度分箱的信息特征维度匹配,将乘性噪声相对稳定的一段时间称为一个时隙,实现数字化信息服务云平台资源置换算法改进.仿真表明,该算法通过资源置换处理,提高信息检索的定位准确率,减少资源分配的运行时间,提高云平台的资源调度分配性能.

Accurate resources displacement of the digital information service cloud platform can improve the data prefetch-ing of cloud platform and resource scheduling ability. The traditional methods information service platform use edge inverse theory of parallel query replacement algorithm for resources displacement of the digital information service cloud platform, thus cannot satisfy the QoS requirements of multimedia data transmission. In this paper purposes a digital information ser-vice cloud platform resources replacement algorithm based on QoS dimensions box. According to the separation theorem of autocorrelation function limit, builds a cache replacement function. back processing. Using the information characteristics of QoS dimension box match dimension, the relatively stable period of multiplicative noise is called a time slot, realize the digital information service cloud platform resources replacement algorithm improvement. Simulation show that the proposed algorithm through resource replacement treatment, improves the positioning accuracy of information retrieval, reduces the running time of resources allocation, improves the cloud platform performance of resource distribution and scheduling.
