拥挤网络市场中的最优服务差异化研究
On Optimal Service Differentiation in Congested Network Markets
摘要：
随着近年来互联网应用变得更加多样化，对在线视频服务有大量需求的用户比主要使用电子邮件和即时消息的轻度用户更愿意为更好的服务支付更高的价格。这促使互联网服务提供商（ISP）探索服务差异化，以优化其利润和网络资源配置。许多先前的工作集中在网络服务差异化的可行性，通过比较的情况下，一个单一的类服务。然而，最佳的服务差异化的ISP资源限制仍然没有解决。在这项工作中，我们建立了一个最优控制的框架来推导出解析解的ISP的最优服务差异化，即最优的服务质量和相关的价格。通过分析解决方案的结构，我们揭示了ISP应该如何调整服务质量和价格，以满足不同的容量约束和用户的特性。我们还获得了条件下，互联网服务提供商有很强的动机，实施服务差异化，以及监管机构是否应该鼓励这种做法。
英文摘要：
As Internet applications have become more diverse in recent years, users having heavy demand for online video services are more willing to pay higher prices for better services than light users that mainly use e-mails and instant messages. This encourages the Internet Service Providers (ISPs) to explore service differentiations so as to optimize their profits and allocation of network resources. Much prior work has focused on the viability of network service differentiation by comparing with the case of a single-class service. However, the optimal service differentiation for an ISP subject to resource constraints has remained unsolved. In this work, we establish an optimal control framework to derive the analytical solution to an ISP's optimal service differentiation, i.e. the optimal service qualities and associated prices. By analyzing the structures of the solution, we reveal how an ISP should adjust the service qualities and prices in order to meet varying capacity constraints and users' characteristics. We also obtain the conditions under which ISPs have strong incentives to implement service differentiation and whether regulators should encourage such practices.
