Data Collection at CAIDA -- Access Requirements

This page is no longer maintained: The CAIDA Data pages have been reorganized in January 2010, and this page is no longer being updated. This page is being retained for archival purposes, but may be removed in the future. The updated, maintained of the datasets indices are found on the CAIDA Data Overview: Overview of Datasets, Monitors, and Reports page.

CAIDA Data by Access Requirements

For a variety of reasons, including respect for the privacy of communication between individuals, security concerns, and the conditions of collection agreements between CAIDA and some of its data providers, we are unable to make all data housed at CAIDA ubiquitously accessible. This page provides an overview of the Acceptable Use Policies under which CAIDA releases data and an index of data sources available with and without these access restrictions.

Funding sources for serving measurement data to the community are both rare and limited. We ask that everyone using CAIDA data send us notification of any publications (including papers, online reports, and theses) that use our data so that we can justify the resources that support our data distribution efforts.

Available on Request	Associated Data
To ensure continued funding for providing data to the Internet measurement community, CAIDA must collect information about the individuals and groups using its data and the goals for research incorporating the data.

CAIDA Visit Required	Associated Data
Some datasets contain sufficiently sensitive information that they cannot be publicly released. These datasets are available to individuals who arrange visits to CAIDA to work on the datasets and return with research results that do not contain sensitive information.
