From renata.teixeira at lip6.fr Thu Dec 2 08:49:52 2010 From: renata.teixeira at lip6.fr (Renata Teixeira) Date: Thu, 02 Dec 2010 17:49:52 +0100 Subject: [sigcomm] Help Us with Measurement Research for Human-Centered Networks Message-ID: <4CF7CE30.5000607@lip6.fr> Dear colleagues, We need your help to conduct our research and are giving away gift certificates! We have designed HostView, a tool that collects network performance data along with user feedback of the network. Traces collected with HostView will help us understand end-user perception of network performance and will guide our research on diagnosing performance problems. To thank you for installing HostView, we are giving away 50$ Amazon gift certificates to 40 users selected at random from the first 100 that run it for a month. You can also ask HostView to give you feedback on the health of your network connectivity and application bandwidth consumption. HostView runs on MAC and Linux PCs. If you are not a Linux or MAC user, please forward this email to your colleagues and friends! Otherwise, please download HostView at: http://cmon.lip6.fr/EMD/Download.html. Once HostView is running there isn't much for you to do, except one thing. HostView includes a "user questionnaire" that should take 1 minute to fill out. We are interested in knowing how you perceive the performance of your machine at various performance points. There are two ways to answer this questionnaire: either when it pop ups (at most 3 times a day) or by hitting the "I am annoyed button" when you are unsatisfied with your network performance. More details on how to answer the questions is in the user manual that you can grab from the EMD project webpage. To see more about the tool and why we have done this, please see our web page at http://cmon.lip6.fr/EMD. A lot has gone into the development of HostView. We have tested and selected particular methods for data collection and data processing so as to have minimal overhead on your machine. A detailed description of HostView is in our Hotmetrics paper (http://hotmetrics.cs.caltech.edu/program.shtml). To address privacy concerns we did a user survey and we designed our tool according to majority opinions from this input (e.g., we included a pause button). The survey results appeared as a short paper in the April 2010 issue of CCR. For your privacy, we have also implemented state-of-the art anonymization techniques. A description of our commitment to your privacy can be found on the project webpage as well. Your help and participation is enormously appreciated!

The workshop, hosted at the University of British Columbia (UBC), will continue to focus on emerging research topics, controversial ideas, and future research directions in the area of multimedia systems research. As in previous years, we will maintain the focused single-track format a setting that stimulates lively discussions among the senior and junior participants. NOSSDAV encourages experimental research based on real systems and real data sets. Public availability of the source code and data sets discussed in papers presented at NOSSDAV is highly encouraged. For NOSSDAV 2011, we will accept papers on broad ranges of topics related to the transmission and presentation of digital audio/video objects. We are particularly interested in soliciting articles that discuss system-level support for distributed social media, as well as papers that focus on enabling multimedia applications in distributed cloud. Other topics of interest include (but are not restricted to): * OS, middleware and network support * Overlay networks * Media streaming, distribution and storage support * Web 2.0 systems and social networks * Media sensor and ad hoc networks / embedded systems * Multicore architecture support * Wireless and mobile multimedia systems / network processor support * Networked GPUs, graphics and virtual environments * Networked games / real-time immersive systems * Multimedia communications and system security * Grid/Cloud computing support Please contact the workshop co-chairs to check if your topic is within the scope of NOSSDAV. Papers will be judged on their relevance, technical content and correctness, and the clarity of presentation of the research. Papers should not be under review at another venue nor previously published elsewhere. Submissions should be at most SIX pages, using standard ACM proceedings style. We expect these submissions to be the kernel of what will eventually lead to full-length papers at high-quality conferences or journals. Important Dates Paper Submission Deadline:24 Feb 2011 Decision Notification: 24 Mar 2011 Camera Ready Due: 7 Apr 2011 For more information, visit the workshop website @ http://nss.cs.ubc.ca/nossdav2011/
