Data tailored to studying the interconnections between devices that compose the Internet. CAIDA's Macroscopic Topology Project runs the team-probing experiment on our Archipelago infrastructure using the scamper tool to generate data for topology datasets. Before February 2008 CAIDA used the skitter tool as basis for topology datasets. The ITDK data kits combine raw skitter topology data with routing tables, router interface data, and contemporaneous IP address hostname lookups. Additional datasets derived from RouteViews include a listing of relationships between Autonomous Systems and an AS taxonomy.

• IPv4 Routed /24 Topology Dataset
• Raw Skitter Topology Traces
• AS Links (AS Adjacencies)
• Router Adjacencies
• Internet Topology Data Kits (ITDK 2002-04 and 2003-04)
• AS Relationships
• AS Taxonomy

In keeping with the global scope of its mission, CAIDA collects data on security events that are widely visible on the Internet, including the backscatter from denial-of-service attacks and the spread of Internet worms.

• Denial-of-Service Attacks
• Backscatter-2008 Dataset
• Backscatter-2007 Dataset
• Backscatter-2006 Dataset
• Backscatter-2004-2005 Dataset
• Backscatter-TOCS Dataset
• Internet Worms
  • Code-Red
  • Witty
• Host Scanning

Data tailored to measuring the traffic flow on the Internet, including analysis of traffic trends, popular applications, malicious activity, and protocol interations. CAIDA houses trace data collected on backbone and major peering links, as well as traces containing information on Domain Name Service (DNS) requests and responses, including public name requests for private address space.

• Backbone and Exchange Point Data
  • Anonymized 2008 Internet Traces Dataset
  • Anonymized 2007 Internet Traces Dataset
  • OC48 traces
• Domain Name Service (DNS) Data
  • DNS root/gTLD RTT Dataset
  • F root server
  • gTLD servers
  • DNS updates for private (rfc1918) Internet address space

Data useful for studying routing behavior on the Internet, including routing table archives and a data kit combining routing information with probed topology data.

• Routeviews Prefix to AS mappings
• University of Oregon RouteViews Archive
• NLANR archived routviews data
• PCH archived routviews data
• Internet Topology Data Kit (ITDK)

CAIDA operates realtime monitors of network traffic at several locations. Displays are generally updated within 15 minutes of collection.

• Coralreef Report Generator

Data useful for evaluating the performance of various aspects of network functioning, including Domain Name Service, IP address space allocation, and core network delay measurements.

• Domain Name Service (DNS) Data
  • root and gTLD servers
  • DNS updates for private (rfc1918) Internet address space
  • DNS root/gTLD RTT Dataset
• Raw Topology Traces containing Intermediate Round Trip Times (RTTs)
