Global Web Cache Latency Measurement for Low-Earth Orbit Satellite Networks: A Dataset
Description
This dataset contains global web cache latency measurements collected via RIPE Atlas probes equipped with low-earth orbit (LEO) satellite networks' terminals across five continents, spanning over 24 hours and resulting in ~2 Million measurements. The measurements aim to evaluate the user-perceived latency of accessing popular websites through LEO satellite networks.
This dataset is a product of Spache, a research project on web caching from space. Please refer to its WWW'25 paper for more details and analysis results.
Dataset File Content
The dataset includes the following files:
Metadata
- Target website list: A list of the top 50 most popular websites according to Alexa ranking.
- Note: microsoftonline.com (originally ranked 41st) is not included in the list due to its unresolvable domain name.
Measurement results - Latency
- Ping RTT latency: Containing the minimum RTT (Round Trip Time, in milliseconds) for each Ping measurement to all target websites.
- Probe information: Corresponding Probe IDs (Anonymized), along with their respective continents at the time of measurement.
This dataset is intended to support research on web caching, particularly in the context of satellite Internet. Please cite both this dataset and the associated paper if you find this data useful.
