I jumped into Internet research in fall 1981 when I started my PhD study at MIT, the same month that the TCP/IP specifications were published. During my eight years of graduate school, my adviser Dr. David Clark taught me how to think architecturally. After graduation I joined Xerox Palo Alto Research Center (Xerox PARC) and spent seven exciting years there (during this time the Internet went from an obscure research to its initial rollout in a global scale), before being recruited to UCLA computer science department. My original plan was to move onto something new once I got a taste of teaching, but that did not happen — it is simply too much fun working with brilliant students and inventing the future together. My mission is to help the Internet grow. See my bio for more details.


PhD student reruiting season is about to start. I am looking for smart, hardworking students who want to contribute to the mission of helping the Internet grow. Here is my expectation on new students.

January 2021

In doing a folder cleanup, I crossed a 2002 paper by Paul Baran that seem worth sharing:
The Beginnings of Packet Switching: Some Underlying Concepts.

I also found the slide deck for a short talk I gave at ACM SIGCOMM 2019 N2Women meeting,
A few lessons from an accidental professor, just to share with whoever interested in taking a look.

November 2020

Internet Archicture Board organized a virtual workshop on COVID-19 Network Impacts. Several of us submitted a whitepaper titled "Identifying the Disease from the Symptoms: Lessons for Networking in the COVID-19 Era".

September 2020

NIST hosted another NDN Comminity Meeting September 10-11, 2020. One can find the recording at

August 2020

I gave a keynote at SIGCOMM 2020, the slides can be found here. People asked many interesting questions, here is the Slack point to that great discussion (including the question "why didn’t IP multicast ever get widely deployed?" that may be interesting to many people)

Named Data Networking

How time flies, especially when one is having fun -- in 2020 we will be celebrate the 10th anniversary of the NDN project which started on September 1, 2010! NDN is going ever stronger with time. We are busy developing more applications over NDN to force out architectural details to be filled in and, most importantly, verifies and shapes the architectural direction.

Here is a partial collection of old papers, showing cumulations of understanding on networking over the years.

Here is a partial collection of recent papers, showing the progress of the NDN development.
