In order to promote a better understanding of the Internet, CAIDA develops new visualization techniques to display Internet data and presents them as poster-sized prints for the research community. These posters are made available for download below.

AS Core Posters
Visualization represents a macroscopic snapshot of the Internet for a two week interval. The graph reflects IP addresses and IP links (immediately adjacent addresses in a traceroute-like path) of topology data gathered from 22 monitors probing destinations spread across globally routable network prefixes.

Visualization represents the monitoring of global Denial-of-Service (DoS) attacks from a single locations. Backscatter analysis is a novel technique that provides DoS activity using only local monitors.
CAIDA seeks to characterize the dynamics and performance of the Domain Name System (DNS), a critical infrastructural component of the Internet. We also collect data in support of long-term research of the DNS behavior and stability. To see more about CAIDA's DNS efforts, see the DNS Research page.
Security research at CAIDA includes analysis of network-based attacks e.g. denial-of-service attacks, data hosting and provision, and measurement and statistical analysis of the trends and impact that certain Internet worms and viruses have on the global network infrastructure.

Archipelago (Ark for short) is CAIDA's next-generation active measurement infrastructure and represents an evolution of the skitter infrastructure that has been serving the network research community for more than 8 years. For more information, see the Archipelago Measurement Infrastructure.
Internet Outages Posters
These posters are produced as the result of an experimental operational deployment to validate and extend an empirically grounded methodology for detection and analysis of large-scale Internet outages. For more information, see Detection and analysis of large-scale Internet infrastructure outages.
Address Space Posters
Internet address space allocation and utilization is visualized here using heatmaps. A heat map is a graphical representation of data where the values taken by a variable in a two-dimensional map are represented as colors.
IPv4 BGP Geopolitical Analysis Poster
The worldwide distribution of Internet resources and address space is highly non-uniform. We present an analysis comparing five demographic measures against three measures of Internet resources, stratified by continent with substratification by country. We found that two continents and one country consume a much larger share of Internet resource allocation than predicted by their demographic measures of size. For more information see IPv4 BGP Geopolitical Analysis.
