Internet Mapping Project
'The Internet Mapping Project was started at Bell Labs in the summer of 1998. Its goal is to acquire and save Internet topological data over a long period of time. This data has been used in the study of routing problems and changes, DDoS attacks, and graph theory.
In the fall of 2000, Ches and Hal moved to a spin-off from Lucent/Bell Labs named Lumeta Corporation. This company applies our topological discovery techniques to discover the perimeter of our clients' intranets. Both Hal and Ches have moved on from Lumeta."
