零费率，一个大麻烦：分析欧洲移动网络运营商的差异化定价实践
Zero-Rating, One Big Mess: Analyzing Differential Pricing Practices of European MNOs
AI总结：
本研究通过300多次受控实验，审计了欧盟七家运营商对四个应用的零费率分类实践，发现几乎所有运营商存在潜在问题行为，旨在提高透明度并影响政策制定。
摘要：
零费率（Zero-rating），即对属于特定应用程序的数据流量不进行计费的做法，已在全球移动生态系统中变得流行。目前存在一场持续的争论：移动运营商是否应被允许对流量进行差异化处理，还是网络中立性法规应阻止这种做法。尽管这一问题十分重要，但由于零费率优惠的实现细节被移动运营商保密，对最终用户和监管机构而言不透明，我们对零费率优惠的技术层面知之甚少。\n 本研究旨在独立审计欧盟七家不同移动运营商对四个流行应用进行零费率时所使用的分类实践。我们在国内和国际漫游环境中执行并评估了超过300次受控实验，并在几乎所有被调查的运营商处发现了潜在的有问题行为。通过这项研究，我们希望提高当前实践的透明度，并为未来的决策和政策提供信息。
英文摘要：
Zero-rating, the practice of not billing data traffic that belongs to certain applications, has become popular within the mobile ecosystem around the globe. There is an ongoing debate whether mobile operators should be allowed to differentiate traffic or whether net neutrality regulations should prevent this. Despite the importance of this issue, we know little about the technical aspects of zero-rating offers since the implementation is kept secret by mobile operators and therefore is opaque to end-users and regulatory agencies. This work aims to independently audit classification practices used for zero-rating of four popular applications at seven different mobile operators in the EU. We execute and evaluate more than 300 controlled experiments within domestic and internationally roamed environments and identify potentially problematic behavior at almost all investigated operators. With this study, we hope to increase transparency around the current practices and inform future decisions and policies.
