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Archipelago measurement infrastructure, that superseded the skitter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.
