系统设计是可伸缩的，如果它可以经济地部署在规模范围内，在小型和大型配置中。对于不同设计的分布式操作软件的可扩展性的度量和比较，人们很少关注。最近，专门为分布式系统定义了一种新的可伸缩性度量（这里称为p -可伸缩性，因为它基于“功率”度量）。本文对该度量进行了推广，定义了一个扩展路径，该路径体现了随着系统的扩展而修改系统的策略，并采用了可伸缩性使能参数，使系统在扩展路径上的任何点上都能给出可伸缩性度量的最大值。
A system design is scalable if it can be economically deployed at a range of scales, in both small and large configurations. Little attention has been paid to measuring and comparing the scalability of different designs of software for distributed operation. Recently a new measure of scalability (called here P-scalability since it bused on the "power" metric) has been defined specifically for distributed systems. The paper generalizes the metric, defines a scaling path embodying a strategy modifying the system as it is scaled up, and employs scalability enabling parameters which adapt the system to give the maximum value of the scalability metric, at any point along the scaling path.
