Barrett Lyon Founds the Opte Project to Map the Internet

In October 2003 Barrett Lyon created the Opte Project, to provide a useful Internet map in computer graphics with open source software. In 2020 it appeared that the project was curtailed in 2015.

"The project started as a concept, using the basic tool of traceroute to map paths and identify common nodes. Realizing that this was an immensely large project, Lyon decided that utilizing a couple computers gathering data with traceroute was simply inefficient, and such a process could take decades to complete. In fact, with the rate data is added to the internet, it’s possible such a project would never be complete. He switched to use instead a native routing protocol of the internet itself, Border Gateway Protocol (BGP). BGP is an essential component of not just the internet, but also represents a common challenge of complex networks in general, finding the shortest path from one stop to another among an increasingly connected web of nodes. BGP determines the shortest possible path among reliability, speed, and other factors set by the operating organization. Each node participating in the organization has a table of suitable “next stops” for a given desired route, this allows one node to forward information to another node, and then finally on to the destination node. Lyon’s idea was to obtain a dump of all BGP-created tables in order to accurately depict the internet.

"Years later, Lyon still uses this process in order to create internet map “art” every five years, most recently in July of 2015. His current workflow involves a much more powerful computer to collect the data. Given the broad scale of the internet, graphs like these that show everything cannot possibly be used for specific investigation, rather they illustrate the vast connectedness of modern society. The Opte Project is showing just how small our world truly is" (https://blogs.cornell.edu/info2040/2016/09/13/the-opte-project-and-visualizing-the-internet/, accessed 9-2020).
