Mapping the Internet


The Internet has grown from the original four nodes in 1969 to an estimated 60 million hosts today.  The central backbone has been replaced by multiple, interconnected backbones.  The Internet's rapid growth and decentralization of control has led to a network whose topology is poorly understood.  The goal of this project is to collect and archive daily Internet topological information for future analysis.  I will discuss the details of the methodology employed, as well as some of the technical and political challenges of mapping the Internet.  I will also review some analysis of the topological information obtained. I will present future work to improve topological discovery, along with additional analyses to perform.


Hal Burch received his B.S. degrees in Applied Mathematics, Computer Science, and Physics from University of Missouri-Rolla in 1997.  He is a third-year doctoral student in the Department of Computer Science at Carnegie Mellon University, where is part of the PSciCo project.  The origin of the work presented is two
summer internships at Bell Laboratories.
