Future online services will be provisioned over the federation of infrastructure providers for economic reasons: for effective usage of resources and for a wide geographic reach of customers. The technical enablers of this setup, envisioned also for 5G services, are the virtualization techniques applied in data centers, and in access and core networks. Business aspects around the provisioning of these services however pose still unresolved questions. In this heterogeneous setup those who want to deploy an online service face the problem of selecting the compute and network resource set that fulfills the technical requirements of the service deployment and that is preferable also from an economic point of view. Infrastructure providers compete among themselves for these customers, and shape their business offerings with profit maximization in mind. We model this resource market with the tool set of graph and game theory in order to study its characteristics. We show that customers need to tackle a hard problem if they want to meet both their technical and business needs, let alone minimizing costs. Furthermore, we derive the best pricing strategies that the providers should follow given their expectation about customers’ demand. Interestingly, we show that equilibrium prices and the attainable income strongly depend on the provider’s location within the network.

NFV基础设施提供商的定价游戏

出于经济原因,将在基础设施提供商联合会上提供未来的在线服务:有效利用资源并扩大客户的地理范围。这种设置的技术推动力(也针对5G服务进行了构想)是应用于数据中心以及接入和核心网络的虚拟化技术。但是,围绕提供这些服务的业务方面仍然存在尚未解决的问题。在这种异构设置中,那些想要部署在线服务的人面临选择满足服务部署技术要求的计算和网络资源集的问题,并且从经济角度来看,这也是优选的。基础设施提供商在这些客户之间相互竞争,并在考虑利润最大化的情况下塑造他们的业务产品。为了研究其特征,我们使用图形和博弈论工具对资源市场进行建模。我们表明,客户要想同时满足其技术和业务需求就需要解决一个难题,更不用说将成本降到最低了。此外,根据客户对客户需求的期望,我们得出了提供商应遵循的最佳定价策略。有趣的是,我们表明均衡价格和可获得的收入在很大程度上取决于提供商在网络中的位置。我们得出了提供商对客户需求的期望应遵循的最佳定价策略。有趣的是,我们表明均衡价格和可获得的收入在很大程度上取决于提供商在网络中的位置。我们得出了提供商对客户需求的期望应遵循的最佳定价策略。有趣的是,我们表明均衡价格和可获得的收入在很大程度上取决于提供商在网络中的位置。
