Abstract

By federating virtualized computing and network resources one can significantly increase their value thanks to gains from statistical multiplexing and increases in resource diversity (more distinct locations, technologies, etc.). Successful federation depends upon resource providers being able to agree on policies: how to share the profit generated by external customers and/or how to allocate the resources contributed by the federation participants to their affiliated users. This paper's main contribution is a method that enables organizers of a federation to evaluate the relative importance of the resources contributed by each participant. We build on coalitional game theory concepts and formulate a generic economic model of federation that captures the notion of diversity, which is relevant for a variety of overlay services, and notably the networking research experiments that are running today on PlanetLab. Based on this model, we propose the Shapley value as a means for participants to share the value of federation. We show how this approach can help in the design of policies that encourage infrastructure owners to federate.
虚拟化基础设施联盟:共享多样性价值
通过联合虚拟化计算和网络资源,可以显著提高它们的价值,这要归功于统计多路复用和资源多样性(更不同的位置、技术等)的增加。成功的联合取决于资源提供者是否能够就策略达成一致:如何分享外部客户产生的利润和/或如何将联合参与者贡献的资源分配给其附属用户。本文的主要贡献是提供了一种方法,使联盟的组织者能够评估每个参与者贡献的资源的相对重要性。我们建立在联盟博弈论概念的基础上,并制定了一个通用的联邦经济模型,该模型捕捉了多样性的概念,这与各种覆盖服务相关,特别是今天在PlanetLab上运行的网络研究实验。在此模型的基础上,我们提出了Shapley值作为参与者分享联盟价值的一种手段。我们将展示这种方法如何帮助设计鼓励基础设施所有者联合起来的策略。
