    Talk Title: Evolving Internet into the Future via Named Data Networking

    Series: CS Colloquium

    Abstract: While the Internet has succeeded far beyond expectations, the success has also stretched its initial design assumptions. Since applications operate in terms of data and more end points become mobile, it becomes increasingly difficult and inefficient to satisfy IP's requirement of determining exactly where (at which IP address) to find desired data.
    The Named Data Networking project aims to carry the Internet into the future through a conceptually simple yet transformational architecture shift, from today's focus on where -- addresses and hosts -- to what -- the data that users and applications care about. In this talk I will present the basic design of NDN and our progress over the last couple years.

    Biography: I joined the faculty of UCLA Computer Science Department in 1995/1996. My research at UCLA started with the design of a global scale web caching system, Adaptive Web Caching (AWC) funded by DARPA (joint work with Van Jacobson and Sally Floyd) and the Internet Distance Map Service funded by NSF (joint work with Paul Francis and Sugih Jamin). A direct follow-up to AWC was GRAB, "Reliable and Robust Sensor Data Collection by Gradient Broadcast" funded by DARPA. In parallel, we also did a number of initial IPv6 development projects. Our group was among the first on the 6Bone and implemented the first IPv6 multicast routing protocol, as well as porting vat and sdr to IPv6.

    Since 1998 much of our focus has been on the deployed global Internet infrastructure. My students and I are currently tackling resiliency and security issues in the global routing system and Domain Name System (DNS), and the system challenges in deploying cryptographic protections in global scale open systems such as the Internet. My group has developed several useful tools that are widely used by the Internet research and operational communities, among them are Internet Topology Collection, Link Rank, Cyclops, SecSpider, and the latest addition EyeP, an IPv4 address allocation and usage visualization tool.

    I coined the phrase "middlebox" in 1999, referring to the new components that were not in the original IP architecture but popped up in many places (web proxies, firewalls, NAT boxes). Much to my own surprise, the word was quickly picked up by the community and it is now used everywhere. In 2008 IEEE Network dedicated a special issue on the "Implications and Control of Middleboxes in the Internet".

    I consider myself fortunate to join Internet research early on. During my 8 years of graduate school at MIT, my adviser Dr. David Clark taught me how to think architecturally. My career goal is to help the Internet grow. I am currently leading a 12-campus research project on the development of a new Internet architecture called Named Data Networking (NDN).
