分析了IP网络服务中不同的服务质量方案给服务提供商带来的经济利益。首先，基于效用理论对IP网络中数据传输的服务质量与用户愿意支付的服务质量之间的关系进行了建模，并通过对网页访问的主观实验对模型进行了验证。该模型解释了WTP是数据传输服务质量的某个功率减去的上限。其次，通过使用WTP模型，我们证明了尽力而为的服务有一个上限来容纳客户以增加提供商的利润，并且利润随着提供商的网络规模的增大而增加。第三，我们证明了具有服务质量优先级控制的服务比只提供尽力而为服务更能有效地提高利润，并且对于市场占有率较小的小服务提供商来说效果尤其显著。
This paper analyzes the monetary profit for service providers according to QoS schemes in IP network services. First, we model the relationship between the QoS in transferring data in IP networks and the amount that customers are willing to pay (WTP) for the QoS based on utility theory, and we verify the model by a subjective experiment in Web page access. The model explains that WTP is an upper limit decreased by some power of the data transfer QoS. Secondly, by using the WTP model, we demonstrate that a best-effort service has an upper limit on accommodating customers to increase the provider's profit, and the profit tends to increase as the provider's network-scale becomes larger. Thirdly, we show that a service with QoS priority control is more effective at improving the profit than only a best-effort service, and the effect is especially noticeable for minor providers with a small market share.
