CAIDA Data

Collection and sharing of data for scientific analysis of Internet traffic, topology, routing, performance, and security-related events is one of CAIDA's core objectives.

|  Data Overview  |

Interested researchers should refer to our Overview of CAIDA Data, a sortable table of dataset attributes, with links to dataset descriptions, request forms (restricted data), download locations (public data), realtime reports, and other meta-data.

Curation of Datasets

CAIDA curates datasets resulting from both active and passive measurement of the Internet. We provide access to these datasets for researchers in accordance with University of California, San Diego policy. We maintain servers that allow researchers to download data via secure login and encrypted transfer protocols.

Active measurement: CAIDA's Macroscopic Topology Project measures connectivity and latency using active probing to a stratified cross-section of the commodity IPv4 and IPv6 Internet.

Passive measurement: CAIDA collaborates with organizations that operate network infrastructure in academic, non-profit, and commercial, and dark address space to passively monitor traffic on selected links, anonymize IP addresses to allow trace sharing, and in some cases publish (close to) real-time statistics of traffic captured from these links.

CAIDA has developed a privacy sensitive data sharing framework that employs technical and policy means to balance individual privacy, security, and legal concerns against the needs of governments researchers, and scientists for access to data in an attempt to address the the inevitable conflict between data privacy and science.

Supporting Publications using Data

CAIDA collects and curates data to provide an empirical foundation for Internet research, maintaining a list of both publications by CAIDA researchers and collaborators, as well as publications by external researchers who report back use of CAIDA data as part of our Acceptable Use Policy (AUP).
