Abstract With the increasing popularity and significance of content delivery services, especially video streaming, stringent Quality of Service (QoS) requirements have been placed upon Internet content providers (CPs). As a result, CPs have strong incentives to pay for resources such as premium peering bandwidth and cache capacity that ameliorate service quality. In this paper, we study an Internet access market with multiple access resources that CPs can purchase to enhance service quality. We build a detailed content delivery model, through which we characterize the traffic throughput and the resulting utilities of CPs and social welfare. We show that a market equilibrium exists for a multi-resource market, at which the optimization problems for individual utilities and social welfare coincide. Furthermore, we characterize the optimal purchasing strategies of CPs as well as how varying parameters are going to change the market equilibrium via sensitivity analysis.

互联网接入市场中的多资源采购：最优策略与市场均衡

摘要 随着内容交付服务的日益普及和重要性，尤其是视频流，对互联网内容提供商（CP）提出了严格的服务质量（QoS）要求。因此，CP 有强烈的动机为可改善服务质量的资源付费，例如高级对等带宽和缓存容量。在本文中，我们研究了一个具有多种接入资源的互联网接入市场，CP 可以购买这些接入资源来提高服务质量。我们构建了一个详细的内容交付模型，通过该模型我们表征了流量吞吐量以及由此产生的 CP 和社会福利的效用。我们证明了多资源市场存在市场均衡，在该市场均衡中，个体公用事业和社会福利的优化问题是重合的。此外，
