摘要: 将Cache技术与主动网络技术结合, 提出了一种新颖的具有有限半径的分布自组织Cache系统.首次提出了相邻Cache树的概念及其生成算法, 分析了相邻Cache树增加的最大最小存储代价, 对内存分配和响应时延之间的关系进行了理论计算, 证明了内存分配的最佳平衡点的存在性, 并给出了一般的求解方法.

Abstract: Integrating cache techniques and active networks, this paper provide a novel distributed and self-organizing wide-area network caches with limited radius. Theconcept of neighbor cache tree and its algorithm is proposed. The max. and themin. storage cost is also analyzed, with the study on the relationship between the partition of memory and the round trip delay, it is proved that there is an optimal cache partitioning point, an average method to find it is discussed in detail.

Key words: active networks, cache, self-organize, wide-area network
