What is it about?
We collect SNESet, an active measurement dataset comprising QoS and QoE telemetry metrics of 8 VSAs over four months, covering end-users from 798 edge sites, 30 cities, and 3 ISPs in one country. We characterize and compare the QoS and QoE metrics in SNESet with existing publicly available datasets, highlighting that SNESet includes a significantly greater number of metrics (horizontal diversity and vertical hierarchy) and provides more comprehensive coverage of specific metrics.

Why is it important?
Our findings can inform the system design decisions that different entities in the video ecosystem (content providers, video player designers, third-party optimizers, edge vendors) make to maximize end-users experience and ultimately maximize the business outcomes. We hope SNESet can attract more research efforts in the data management community, computer network community, and beyond.
Perspectives
I am very grateful to the Alibaba edge computing team for their support in open-sourcing such a large-scale data. We also hope to attract more researchers to conduct in-depth research on large-scale edge computing platforms, including networks, systems, data management, etc.
