Hosting provider PEER 1 set out on a mission to design a visually compelling Map of the Internet and it looks pretty cool.
The company used Internet topology data available from the Cooperative Association for Internet Data Analysis (CAIDA) to depict an infographic of 19,869 autonomous system nodes joined by 44,344 connections. Each autonomous system is a network operated by a single organization, and has routing connections to some number of neighboring autonomous systems.
The sizing and layout of the autonomous systems are based on their eigenvector centrality, which is a measure of how central to the network each autonomous system is: an autonomous system is central if it is connected to other autonomous systems that are central. This is apparently the same graph-theoretical concept that forms the basis of Google’s PageRank algorithm.
You can read more about the Map of the Internet as well as download images of the infographic here.
If you're attending South By Southwest (SXSW) later this month, PEER 1 is giving away free limited edition 24"x36" poster prints at their booth.
