This page is no longer maintained: The CAIDA Data pages have been reorganized in January 2010, and this page is no longer being updated.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 Tool
Tool development is an integral part of the research performed at CAIDA for the simple reason that without robust, scientifically rigorous data collection, no network research can be accomplished. CAIDA aims to develop and release tools that support valid scientific inquiry by detecting and reporting errors that occur during data collection. The following datasets were collected using tools developed by CAIDA and other network researchers to support ongoing efforts to study the Internet.
| CoralReef Software Suite | Associated Data |
|---|---|
|
CAIDA's CoralReef Software Suite provides a system of drivers, libraries, and programs to support network data capture and analysis. An extension of the earlier OCXMON software, CoralReef allows users to collect and output passive traces in a variety of formats, read, display, and process traces collected elsewhere, and even display dynamic, configurable, real-time traffic reports. |
|
| Scamper | Associated Data |
|
The scamper tool is used in the Archipelago measurement infrastructure, that superseded the skitter measurement infrastructure. |
|
| Skitter | Associated Data |
|
The skitter tool, supporting CAIDA's Macroscopic Topology Project, facilitates the active collection of IP-level topology data on the Internet. Skitter iteratively probes the path to a provided list of destinations, allowing collection of a "snapshot" of a network path traversed between a source and a destination. Skitter can also return such information as Intermediate Round Trip Time (RTT) and ICMP errors encountered during a measurement. Data collected by skitter is available in its raw format, as an aggregated AS adjacency matrix, and as a part of CAIDA's Internet Topology Data Kit (ITDK). |
|
| IFFinder | Associated Data |
|
The iffinder tool discovers connections between router interfaces, including identifying interfaces beloning to a single router. The resulting router adjacency matrix is available both standalone and as a part of CAIDA's Internet Topology Data Kit (ITDK). |
|
| NeTraMet | Associated Data |
|
Nevil Brownlee's NeTraMet traffic monitor provides a sophisticated interface to traffic collection, including a programmable interface to collect packet and flow data. It exports collected data via SNMP (to support data processing in other tools as well as human readable text outputs). NeTraMet is configurable using a standardized programming language defined by the IETF. It can perform sophisticated analysis, including calculating Round Trip Time (RTT) and packet size distributions, to reduce the volume of exported data. |
|
| NetGeo | Associated Data |
|
CAIDA's NetGeo tool provided an early heuristic-based approach to the geolocation of Internet entities such as IP addresses and Autonomous Systems (ASes), as well as an index to whois database records. The combination of a lack of continued funding to support the project and the availability of equally accurate (country-level granularity) commercial products, including Digital Envoy's NetAcuity product, led CAIDA to stop supporting the NetGeo project. While the server is still available, the data supporting queries was last updated in 2001 . NetGeo is no longer a viable support tool for Internet research; we strongly discourage its use and we urge anyone in search of accurate geolocation data to use an alternate solution. |
