Democratic principles, from the freedom of speech, to fair business practices, rely on Net neutrality, i.e. equal access to communication infrastructure and services. While a number of national and international regulations stipulate Net neutrality, the actual enforcement is challenging as regulators have to collect and analyze a large amount of network measurements, and pinpoint cases of neutrality violations. Through a large-scale distributed crowdsourced measurements campaign, the Agency for Communication Networks and Services of the Republic of Slovenia (AKOS) has acquired a massive dataset of Internet performance measurements in Slovenia. In this work we analyze about one million multi-dimensional data records gathered by the AKOS Test Net measurement system and identify the practices, such as port blocking, that might violate Net neutrality principles. We then chart the limitations of the employed measurement approach and propose a holistic multi-stakeholder approach ensuring high quality measurement data upon which reliable Net neutrality violation inferences should be based.

迈向整体网络中立违规检测系统：斯洛文尼亚案例研究

民主原则，从言论自由到公平的商业行为，都依赖于网络中立性，即平等获得通信基础设施和服务。虽然许多国家和国际法规都规定了网络中立性，但实际执行具有挑战性，因为监管机构必须收集和分析大量网络测量数据，并查明违反中立性的案例。通过大规模分布式众包测量活动，斯洛文尼亚共和国通信网络和服务机构 (AKOS) 获得了斯洛文尼亚互联网性能测量的海量数据集。在这项工作中，我们分析了 AKOS 测试网测量系统收集的大约一百万条多维数据记录，并识别了一些做法，例如端口阻塞、这可能违反网络中立原则。然后，我们绘制了所采用的测量方法的局限性，并提出了一种整体的多利益相关者方法，确保高质量的测量数据，可靠的网络中立违规推断应该基于这些数据。
