摘要
Internet web应用程序由不时更新的动态web对象组成。这项工作研究了web对象在多层服务器上的放置，其中每个主机可以通过本地构建或通过来自上游主机的网络传输获得对象。维护web对象的成本包括用于构造对象的计算资源和用于对象交付的网络带宽。本文提出了一种新的高效算法来寻找成本最小的目标放置策略。
Minimum Cost Content Object Reconstruction in Multi-tier Servers
An Internet web application is comprised of dynamic web objects that are updated from time to time. This work investigates the placement of web objects over multi-tier servers in which each host can obtain an object by constructing locally, or via a network transmission from the upstream host. The cost of maintaining web objects consists of the computing resources used for constructing objects as well as the network bandwidth used for object delivery. This paper develops a new efficient algorithm to find the minimum cost object placement strategy.
