Proceedings of the 21st ACM Workshop on Hot Topics in Networks

It is our pleasure to welcome you to the tenth ACM SIGCOMM Workshop on Hot Topics in Networks---HotNets X. As with previous instances of this workshop, the goal has been to provide a venue for publication and discussion of early-stage, provocative research. We received 119 submissions and accepted 24 papers. The accepted papers cover topics ranging from novel network architectures to wireless networks, data center networks, energy, privacy and security issues. Like many conferences, we adopted a 2-round review process. Our program committee wrote over 450 reviews to ensure every paper received at least 3 reviews, with a little more than half the papers proceeding to the second round and receiving at least 2 additional reviews. Nearly 60 papers were discussed in the full-day PC meeting. We aimed to ensure that highly innovative work would be accepted even if not quite "fully baked", and encourage papers that identify fundamental open questions, or offer a constructive critique of the state of networking research. In achieving this goal, we were helped by the high quality of submissions, and the incredibly thorough reviews and positive discussions during the PC meeting. While there were papers that produced divided opinions among the PC, we were able to converge and achieve consensus on the accepted papers in a constructive manner.
