Networks that carry application data can apply differential treatment, e.g., by giving different performance to different applications and providers. Such behavior is colloquially referred to as net neutrality violations, and formally as traffic differentiation. For example, in U.S., video streaming is often artificially limited to low data-transfer speeds, meaning that only low-quality video can be supported. Further, this is sometimes done only to certain video-streaming providers, creating an unlevel playing field. This project supports the Wehe software ecosystem, which provides mobile apps and other software that reveals when network providers differentiate service and publishes results for stakeholders. Wehe requires continual maintenance so that Wehe tests continue to correctly identify when they experience differentiation. To address this, this project will bring Wehe software into compliance with current operating systems and apps that experience differentiation and produce strategies to make Wehe more resilient to future changes. Second, Wehe does not isolate which network is responsible for differentiation. To improve Wehe’s ability to identify the correct network responsible for net neutrality violations, this project will develop new statistical methods based on network performance tomography and implement new tests in Wehe that leverage these methods to reliably identify the network responsible for differentiation.The project work will benefit Internet subscribers, policy makers, and service providers by revealing violations of net neutrality, and ensuring that policy decisions are informed by empirical evidence. Internet subscribers can learn whether their providers violate net neutrality via the Wehe mobile app, the general public can see aggregate findings on net neutrality via a public Web site for reporting Wehe results, and findings from the project will be shared with stakeholders such as policy makers. Subscribers will benefit from transparency and understanding alternative options, and content providers can adjust their applications to improve efficiency. The project will also identify unintended negative side-effects of middleboxes, and produce recommendations to improve network efficiency.Details about the project, its findings, and other artifacts are located at: https://wehe.meddle.mobi. The project has produced public datasets, software, results, visualizations, and other insights for six years. The goal is to continue publishing and updating such artifacts in perpetuity, or for as long as the project is relevant.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

携带应用程序数据的网络可以应用差异处理，例如，通过为不同的应用程序和提供商提供不同的性能。这种行为被称为违反网络中立性的行为，并正式地称为流量差异。例如，在美国，视频流通常人为地限于低数据传输速度，这意味着只能支持低质量的视频。此外，这有时仅针对某些视频流提供商，创建一个不升级的竞争环境。该项目支持WEHE软件生态系统，该系统提供移动应用程序和其他软件，这些软件揭示了网络提供商何时区分服务并为利益相关者发布结果。 Wehe需要持续维护，以便WEHE测试继续正确地确定何时差异化。为了解决这个问题，该项目将使Wehe软件符合当前的操作系统和应用程序，这些操作系统和应用程序会经历差异化并产生策略，以使Wehe对未来的变化更具弹性。其次，Wehe不隔离哪个网络负责差异化。为了提高WEHE确定负责网络中立性违规的正确网络的能力，该项目将基于网络绩效断层扫描的新统计方法，并在WEHE中实施新的测试，以利用这些方法来可靠地识别负责差异的网络。互联网将使互联网订阅者，政策制定者，政策制定者和服务提供者通过侵犯净中立性的侵犯，并确定净额决策。互联网订户可以通过WEHE移动应用程序了解其提供商是否违反网络中立性，公众可以通过公共网站看到网络中立性的总发现，以报告WEHE结果，并且该项目的发现将与政策制定者等利益相关者分享。订户将受益于透明度和理解替代选择，内容提供商可以调整其应用程序以提高效率。该项目还将确定中间箱的意外负面副作用，以及提高网络效率的生产建议。有关该项目，其发现和其他文物的详细信息位于以下位置：https：//wehe.meddle.mobi。该项目已生产了六年来生产公共数据集，软件，结果，可视化和其他见解。目的是继续在永久性上发布和更新此类文物，或者只要该项目相关。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，通过评估被认为是珍贵的支持。
