It is because of these achievements that he has received the honor of the 2023 IEEE Computer Society Harry H. Goode Memorial Award for “…significant and pioneering contributions to algorithms, protocols and architectures for routing in computer networks and the Internet.” Join us as we dive more into the mind of Dr. J.J. and learn more about his history below.
You’ve made countless contributions and advancements within the field of algorithms, protocols and architectures. What has been the most rewarding part of your work?
The most rewarding part of my work has been sharing the excitement with my students of coming up with new problems, finding new ways to view them, and inventing new solutions (algorithms, protocols, or architectures) to solve them. Just as rewarding as this has been seeing that many researchers have studied my work and used it to create their own new ideas and solutions.

Your work has focused extensively on routing algorithms and protocols. How have these technologies evolved over the course of your career, and what do you see as the biggest challenge facing routing research today?
By its very nature, routing is a very challenging problem, and I love working on routing because of it. Routing technology has continued to evolve over the years. This is easy to explain, because routing technology is intended to help deliver the right information to the right recipients at the right time as safe and efficient as possible– even as the sources or receivers of information and the networks it’s being transferred over change dynamically. This prior statement is changing continuously as demand, technology, and use cases of networks evolve. Routing in networks was different before the advent of packet switching, what routers and switches could do when packet switching was deployed, and what servers could run 10 or 20 years ago is very different from what can be done today.
One of the biggest challenges facing routing today is that many companies and funding agencies may view routing as a solved problem or not a very important one, simply because routing is taking place on the Internet, the IoT, and wireless networks; many international standards for routing have been adopted by vendors; and software define network (SDN) controllers can always be used. The fact is that such protocol standards as OSPF, OLSR, EIGRP, BGP, or the software running in SDN controllers, are based on very limited algorithms that assume the use of very limited machine intelligence and memory. They date back 40 to 50 years.
Future routing algorithms and protocols can take into account user intent, policies, network conditions and context, administrative constraints, multiple time-scales of communication, multiple optimality criteria, and security and privacy considerations, and do so in a distributed manner.
Your paper, “An Efficient Routing Protocol for Wireless Networks” (Mobile Networks and Applications Journal, 1996) has been cited more than 2100 times. Did you expect such a response and how did it feel to make such an impact? Were there many people who reached out to you?
I did not expect so many citations for that paper, but it’s very rewarding because I wrote it with my first Ph.D. student at UCSC, Shree Murthy. The impact of my work on routing has been less focused on a single paper and more on the aggregate body of results on the theory and practice of routing described in my papers. Most of the researchers influenced by my work have cited my papers, rather than reaching out directly to me; however, I have had the opportunity to be part of great research teams including SRI International, Nokia, PARC, and BBN, because of my published results on routing.
With such a successful career, you’ve overcome so many challenges! Is there any advice you wish you had received at the start of your career? If so, what would it be? Is there any advice you received that contributed to your success?
As a graduate student and a junior researcher, I tended to believe that approaches and results published in standards, important venues, or by well-known researchers must have been right. Over time, I realized that all research results have limitations, which stem from the researchers’ research foci and the technological context within which the results were derived. I now advise my students to always challenge conventional wisdom when they approach a research problem, and to not believe that a result is true or the best approach simply because it is an international standard, a “well-known” result, or a result published by a great research team. Just like no one would think that cars designed 50 years ago constitute the best designed cars, researchers in any technological field need to consider the fact that inventions produced many years ago were limited by the technological context when the inventions and designs were produced.
Frank Kuo, my thesis advisor at the University of Hawaii at Manoa, let me know early on during my graduate studies that being smart is only a small part of being a successful researcher. Learning constantly what others have done or are doing, and working very hard to build from that shared knowledge are critical. Frank also made me understand how important it is for a researcher to write clearly and succinctly in order to convey research results to the intended readership. I have remembered these and many of other of his valuable lessons, and passed them on to my students the best I could over the years.
