March 2020: I am serving, together with Peter Steenkiste, as Program co-Chair for the ICNP 2020 conference. That will be held in Madrid, Spain, in October. Please consider submitting to the conference. It is single-track and of high quality. The abstract registration deadline is 11:59pm EDT (midnight) on May 19, 2020, with full papers due by 11:59am (noon) on May 26, 2020.
December 2019: The paper titled "Pricing (and Bidding) Strategies for Delay Differentiated Cloud Services" co-authored with my Ph.D. student Jiayi Song has been accepted for publications in the ACM Transactions on Economics and Computation (TEAC). Here is a temporary link to the paper, while waiting until the final version is available on the ACM DL.
August 2019: The 2019 ACM SIGCOMM conference was successfully held for the first time in China in Beijing. Our thanks to Jianping Wu and Wendy Hall, the two General Chairs, as well as Yong Cui and Xiangyang Li, the two vice-Chairs for a very successful conference that shattered past attendance records. If you go to the conference Program page, you will find links to the papers and their slides as well as streamed videos from all the sessions. Enjoy!
April 2019: My former student, Soumya Sen, is now a recently promoted and tenured Associate Professor in the Department of Information Systems & Decision Sciences at the Carlson School of Management of the University of Minnesota, and furthermore was named a 2019 McKnight Presidential Fellow at the University of Minnesota. Quoting from their website, “The McKnight Presidential Fellows Program is a three-year award given to the most promising individuals who have been granted both tenure and promotion to associate professor in an academic year. It recognizes recipients who are recommended by their college dean and chosen at the discretion of the executive vice president and provost based on excellence in research and scholarship, leadership, potential to build top-tier programs, and ability to advance University of Minnesota priorities.” Congratulations to Soumya and well-deserved.
Our IPv6 Monitoring project gathered several years of data on IPv6 adoption and tracked basic web performance when accessing web sites over either IPv6 and IPv4 to determine if and why differences were present. Most of the data remains available on the project web site that also boasts a “query” page that allows you to customize the type of data you want to retrieve. (See the project's original introductory presentation -the audio unfortunately only starts about 7 mins into the presentation- given at the Summer 2010 ESCC/Internet2 Joint Techs conference). The project started as a joint project with Comcast and was subsequently supported by an NSF grant that enabled us to better explore the data we were gathering as well as improve the web interface that provides access to the data. The insight derived from the data gathered as part of this project was ultimately documented in a paper titled “Migrating the Internet to IPv6: An exploration of the when and why,” co-authored with M. Nikkhah and published in 2016 in the IEEE/ACM Transactions on Networking.
