Welcome to the UCLA Computer Science Department's Internet Research Lab (IRL). IRL's research areas include fault tolerance in large scale distributed systems, Internet routing infrastructure, Inter-domain Routing (BGP), and protocol design principles for large-scale, self-organizing systems. You can find a list of our latest funded projects here.

The Internet Research Laboratory's research projects are guided by Dr. Lixia Zhang, Professor at UCLA.

  • October 2008
    It is commonly recognized that the Internet AS-level topology inferred from publicly available BGP data is incomplete, however there has been no quantitative estimate on exactly how incomplete the inferred topology might be. We addressed this question in a recent technical report, "Quantifying the Completeness of the Observed Internet AS-level Structure"
