Measuring the Internet's susceptibility to spoofed source address IP packets, we generate a summary report on the current "state" of Internet IP source address spoofing/filtering using data from an active measurement tool.

This page describes KISMET, a CAIDA project of the NSF Convergence Accelerator program.

The MANIC project -- Measurement and Analysis of Interdomain Congestion -- has developed a prototype system to monitor interdomain links and their congestion state, in order to provide empirical grounding to debates related to interdomain congestion.

CAIDA developed an operational prototype system that monitors the Internet, in near-realtime, with the goal of identifying macroscopic Internet outages affecting the edge of the network, i.e., significantly impacting an AS or a large fraction of a country.

The Information Marketplace for Policy and Analysis of Cyber-risk & Trust (IMPACT) project provides vetted researchers with current network operational data.

Named Data Networking is a proposed Internet architecture that replaces IP with a network layer that routes directly on content names.

The goal of this IRNC Special Project was to identify and support the measurement priorities of the International Research Network Connections community.

A measurement-driven exploration of the evolution of IPv6.

Named Data Networking is a proposed Internet architecture that replaces IP with a network layer that routes directly on content names.

From 2010-2013, CAIDA performed a study of the economics of Internet interconnection.

The Cybersecurity project proposes to develop and implement new measurement and data collection technologies to understand and protect essential U.S. informational infrastructure.

The purpose of the SD-NAP is to facilitate efficient interconnection of Internet Protocol transit networks within and to the San Diego Local Access and Transport Area, California LATA 6, and to provide a platform for traffic analysis by CAIDA researchers, with the goal of promoting a robust, scalable global Internet infrastructure.

The goal of the Trends project is to create and populate the Internet Measurement Data Catalog (IMDC) that will facilitate access, archiving, and long-term storage of Internet data as well as sharing the data among Internet researchers.

As an extension of the IEC project, CAIDA helped develop Internet Teaching Laboratory (ITL) facilities at several U.S. colleges and universities.

The Internet Atlas project involved developing techniques, software, and protocols for mapping the Internet, focusing on Internet topology, performance, workload, and routing data. It also includes assessment of state-of-the-art in this nascent sector.

The Internet Engineering Curriculum Repository is a projectto help educators and others interested in Internet technology keep up with developments in the field.

We conducted passive and active measurements of the DNS root servers behavior, connectivity and performance. We also analyzed data collected at the servers themselves.

CAIDA researchers have been collecting connectivity and latency data for a wide cross-section of the commodity Internet since 1998 for the IPv4 address space and since 2003 for the IPv6 address space. We use these data to derive maps of the Internet at various granularity levels: IP, router, AS.

DITL is a product of the effort of CAIDA, ISC, DNS-OARC, many partnering root nameserver operators and other organizations to coordinate and conduct large-scale, simultaneous traffic data collection events with the goal of capturing datasets of strategic interest to researchers.

We propose to improve existing techniques and tools for bandwidth estimation, and to test and integrate them into Department of Energy (DOE) and other network infrastructures. The proposed effort will overcome limitations of existing algorithms whose estimates degrade as the distance from the probing host increases.
