The Twelfth ACM Workshop on Hot Topics in Networks (HotNets-XI) will bring together researchers in computer networks and systems to engage in a lively debate on the theory and practice of networking. HotNets will provide a venue for debating broad future research agendas in networking and for presenting innovative ideas that have the potential to significantly influence the community.

We invite researchers and practitioners to submit short position papers. We are particularly interested in papers that foster discussion of broad research agendas for the networking community as a whole. We strongly encourage papers that identify fundamental open questions, or offer a constructive critique of the state of networking research.

We also encourage submissions of early-stage work describing enticing but unproven ideas. Such papers could, for example, advocate a new approach, re-frame or debunk existing work, report unexpected early results from a deployment, or propose new evaluation methodologies. Once fully developed and evaluated, the work may be relevant to conferences such as SIGCOMM, SOSP, OSDI, SenSys, NSDI, MobiCom, MobiSys, PODC, CoNEXT or INFOCOM.

HotNets takes a broad view of networking research. This view includes new ideas relating to (but not limited to) data center networks, home and enterprise networks and wide area networks using a variety of link media (wired, wireless, acoustic) as well as social networks and network architecture. It encompasses all aspects of such networks, including (but not limited to) provisioning and resource management, economics and evolution, robustness and security, topology, mobility, interactions with applications, usability of underlying networking technologies, energy, performance, measurement and diagnosis, and hardware.

Position papers will be selected based on originality, likelihood of spawning insightful discussion at the workshop, and technical merit. Accepted papers will be posted online prior to the workshop and a workshop summary will be published in ACM SIGCOMM's Computer Communication Review (CCR), thereby widely disseminating the ideas discussed at the workshop.
