CAIDA collects several different types of data at geographically and topologically diverse locations, and makes this data available to the research community to the extent possible while preserving the privacy of individuals and organizations who donate data or network access.
This page provides a quick-access overview of completed datasets (publicly available or otherwise restricted) or datasets that were generated as a one-time snapshot, with links to the dataset descriptions and access request forms when applicable. To read more about CAIDA's efforts in data curation and promoting data sharing, see the main CAIDA Data page.
The colored header in the overview table below indicates the field(s) the table is being sorted by. Click the header to change or toggle sorting order, and Shift+click headers to sort by multiple fields. To see ongoing datasets, see the main CAIDA Data Overview table. Rows are colored by the collection status of the indicated dataset as follows:
|Ongoing||The data collection for this dataset is still active and has continuing, regularly scheduled collections. See the CAIDA Data Overview for Ongoing datasets.|
|One-time snapshot||The dataset comes from a single collection event that only occured once. Future events will have a different dataset name.|
|Complete||A formerly ongoing data collection that is finished, and will not be resumed.|
|Column Name||Column Description|
|Status||Current status of this dataset, indicating whether the dataset collection is ongoing or not. "One-time snapshot" implies complete. A link to resulting papers or analysis would be linked from the status, if available..
|Availability||Public datasets are downloadable per the Acceptable Use Policy for the dataset. Restricted datasets require prior permission as well as adherence to the Acceptable Use Policy for that dataset. If a dataset requires a formal request for usage, the form will be linked.|
|Category||Our taxonomy of the general category this dataset belongs in.|
|Source||The source (e.g., network monitors, measurement infrastructure, etc) used to collect the dataset.|
|Start Date||The date when the data collection started.|
|End Date||The date when the data collection ended.|
Other organizations across the globe, both academic and non-academic, provide access to internet-related data that also are of interest to the research community. Links to several of the more interesting datasets are given in a non-exhaustive list of external (non-CAIDA) data.
