Featured Collections and Publications
- CAIDA skitter AS Links Topology
- 2854 files, 2000‑01‑02 to 2008‑02‑08
- Autonomous system (AS) topology derived from skitter traces (an AS is roughly
an ISP). Possible uses include studying statistical and topological properties
of AS graphs, constructing realistic Internet topologies for modeling and
simulation, and studying AS relationships. Data collection has been continuing
for over 7 years as of 2007.
- CAIDA Witty Worm Data, public access
- 7 files, 2004‑03‑20 to 2004‑03‑25
- Information useful for studying the spread of the Witty worm, as observed by
the UCSD Network Telescope over a 5-day period in Mar 2004. This dataset
consists of public-access files that do not individually identify infected
computers. Data available include time, duration, country, and connection speed
distributions of infected hosts. This public-access dataset does not include
packet traces of traffic generated by infected hosts. Possible uses include
modeling worm propagation. Statistics: 55,909 infected IP addresses.
- CAIDA OC48 Traces 2003-04-24
- 26 files, 2003‑04‑24 to 2003‑04‑24
- Anonymized packet header traces collected in both
directions of an OC48 link on Apr 24, 2003 (1
hour). This link is a west coast peering link for a large ISP. Possible uses
include research on the characteristics of traffic, including application
breakdown, security events, geographic and topological distribution, and flow volume and
duration. Statistics (both directions): 13GB of traces, 203 million packets,
and 96GB of observed IP traffic.
- CAIDA Backscatter-2004-2005
- 63 files, 2004‑05‑26 to 2005‑12‑01
- Information useful for longitudinal study of denial-of-service (DoS) attacks.
This dataset consists of 5.5 billion IPv4 packets sent by DoS attack victims in
response to spoofed attack traffic. This backscatter from victims was collected
by the UCSD Network Telescope, one week of data per quarter, between May 2004
and November 2005. Possible uses include modeling DoS attacks, understanding
victim populations, and using real packet traces to validate algorithms for
detecting or classifying malicious traffic. This last use is particularly
valuable because it is extremely challenging to artificially generate the kind
of real-world noise present on the Internet.
