【摘要】:为了使路由器的缓存大小配置合理,首先综合考虑路由器的度数权重、紧密度、网络的中心度、请求影响度等度量指标,定义了一个新的度量指标,称为节点权重;然后提出一种基于节点权重的缓存大小分配方案,将网络所需的容量按比例分配给路由器。仿真结果表明,与均匀分配相比,路由器的缓存空间利用率至少提升了8%,命中率至少提高了6%;与基于请求影响度的分配方案相比,路由器的缓存空间利用率至少提升3%,命中率至少提高了3%。
[Abstract]:In order to make the buffer size of router reasonable, a new metric, called node weight, is defined by considering the degree weight, compactness, network centrality and request impact degree of the router. Then, a buffer size allocation scheme based on node weight is proposed, which distributes the network capacity to the router proportionally. The simulation results show that, compared with the uniform allocation, the cache space utilization rate of the router increases at least 8%, the hit rate increases at least 6%, and compared with the allocation scheme based on request impact degree, Router cache space utilization at least 3 increase, hit rate at least 3 increase.
