摘　　要：为避免多频道重叠网中下载数据与传输线路的关联度对动态缓存效果造成的影响,构建多频道重叠网下载数据动态缓存数学模型。对多频道重叠网的拓扑结构进行解析,充分考虑多频道重叠网的动态性和灵活性。根据解析结果计算下载数据的下载速率均值及连接度特性,从而更准确地预测下载速率的平均值。根据上述特性设定数据的下载队列,评估不同节点之间的连接强度和信道利用率,优化下载队列的组织方式。基于此构建下载数据缓存数学模型,设定动态缓存门限策略并添加到数学模型,实现下载数据的动态缓存,满足不同的网络负载和用户需求。实验结果表明:所提方法应用后表现出的字节命中率较高,均值可达0.9405,效果较优,满足了多频道重叠网运行的现实需求。To avoid the impact of the correlation between downloaded data and transmission lines on dynamic caching performance in multi-channel overlapping networks,a mathematical model for dynamic caching of downloaded data in multi-channel overlapping networks is constructed.Analyze the topology structure of multi-channel overlapping networks,fully considering the dynamics and flexibility of multi-channel overlapping networks.Calculate the average download rate and connectivity characteristics of the downloaded data based on the analysis results,in order to more accurately predict the average download rate.Set the download queue for data based on the above characteristics,evaluate the connection strength and channel utilization between different nodes,and optimize the organization of the download queue.Based on this,a mathematical model for downloading data caching is constructed,and a dynamic caching threshold strategy is set and added to the mathematical model to achieve dynamic caching of downloaded data,meeting different network loads and user needs.The experimental results show that the proposed method exhibits a high byte hit rate after application,with an average of 0.9405,which is excellent and meets the practical needs of multi-channel overlapping network operation.
