AutoFocus

AutoFocus is a traffic analysis and visualization tool that describes the traffic mix of a link through textual reports and time series plots.

Beluga

Beluga provides a real-time graph of RTTs and packet loss to an end host, showing both total round trip time and per-hop round trip time. It also shows a historical statistical breakdown of RTTs, to allow trend analysis.

cflowd

cflowd is a flow analysis tool currently used for analyzing Cisco's NetFlow enabled switching method. The current release (described below) includes the collections, storage, and basic analysis modules for cflowd and for arts++ libraries. This analysis package permits data collection and analysis by ISPs and network engineers in support of capacity planning, trends analysis, and characterization of workloads in a network service provider environment. Other areas where cflowd may prove useful include usage tracking for Web hosting, accounting and billing, network planning and analysis, network monitoring, developing user profiles, data warehousing and mining, as well as security-related investigations.

CoralReef

CoralReef is a comprehensive software suite developed by CAIDA to collect and analyze data from passive Internet traffic monitors, in real time or from trace files. Realtime monitoring support includes system network interfaces (via libpcap), FreeBSD drivers for Apptel POINT (OC12 and OC3 ATM) and FORE ATM (OC3 ATM) cards, and support for Linux and FreeBSD drivers for Endace DAG (OC3 and OC12, POS and ATM) cards. The package also includes programming APIs for C and perl, and applications for capture, analysis, and web report generation. This package is maintained by CAIDA developers with the support and collaboration of the Internet measurement community. CoralReef is the evolutionary successor of the Coral package and supersedes it.

dsc

dsc is a system for collecting and exploring statistics from busy DNS servers.

iffinder

The Skitter project discovers IP interfaces and how they're connected. To make these data more useful, we must also discover which of these interfaces belong to the same router. Iffinder, developed by Ken Keys at CAIDA, is a tool that attempts to do this.

Mantra

Mantra (Monitor and Analysis of Traffic in Multicast Routers) is a tool for monitoring various aspects of multicast at the router level. The results from Mantra are aimed to depict the snapshots of various constituents of the multicast infrastructure from the point of view of the router/s that we are monitoring. These snapshots, presented in several different modes, form the basis (and the main objective!) of this site. Results presented here are updated every 15-30 minutes.

NeTraMet

NeTraMet is an open-source (GPL) implementation of the RTFM architecture for Network Traffic Flow Measurement, developed and supported by Nevil Brownlee at the University of Auckland. Nevil also developed a version of NeTraMet which uses the CoralReef library to read packet headers. This 'CoralReef NeTraMet meter' can work with any CoralReef data source; it has been tested on both CAIDA and NLANR trace files, and on DAG and Apptel ATM interface cards.

RTG

RTG is a flexible, scalable, high-performance SNMP statistics monitoring system. It is designed for enterprises and service providers who need to collect time-series SNMP data from a large number of targets quickly.

scamper

Like its predecessor skitter, scamper is a tool that actively probes the Internet in order to analyze topology and performance. Unlike skitter, scamper supports both IPv6 and IPv4 path probing. It can also discover the maximum transmission unit (MTU) of a given path. Eventual deployment of scamper monitors will extend CAIDA's Macroscopic Topology Project to cover the growing IPv6 topology.

skitter

skitter is a tool for actively probing the Internet in order to analyze topology and performance.
