@misc{12374, author = {Carsten Griwodz and Lars Wolf}, title = {Proceedings of the 18th International Workshop on Network and Operating Systems Support for Digital Audio and Video (NOSSDAV)}, abstract = {The 18th Annual International Workshop on Network and Operating Systems Support for Digital Audio and Video was held at TU Braunschweig, the oldest technical university in Germany. As always at NOSSDAV, new and controversial ideas and approaches were presented and discussed, and young and experienced researchers met for lively discussions. To strengthen this aspect of the workshop, we arranged NOSSDAV 2008 under the dual sign of interactivity. Firstly, we particularly encouraged submissions to the topic of system support for interactive multimedia, and of course, we expected the intense discussions that are usual for NOSSDAV and set it apart from many other conferences and workshops. As promised in the call-for-papers, interactivity plays a major role in many of the papers presented at this year{\textquoteright}s NOSSDAV. Secondly, we had a separate call for demonstrators of research systems and prototypes. This results in a strong demonstration program that allows participants to see and interact with research systems and prototypes in practice. Overall, the workshop featured the presentations of 17 research papers by authors and presenters from 16 countries. The paper topics include network and operating system support, new use of multimedia services, the understanding of multimedia workload and streaming with specific environments or applications. Furthermore, a dozen prototypes and systems are exhibited in the demonstration session. Moreover, NOSSDAV 2008 comprises a strong invited program as well. The keynote speech of NOSSDAV 2008 will be given by Professor J{\"o}rg Liebeherr, University of Toronto. In his keynote entitled "Overlays can do more ... if not everything", he claims that the fundamental limits of overlay networking remain largely unexplored, and presents the challenges of large numbers of co-existing overlays. The invited talk by Paulo Mendes of INESC entitled "Cooperative Networking as Boosting Tool for Internet Interactivity" will show us that cooperative networking appears at several layers of the network stack and start a discussion on conditions for successful or failing systems.}, year = {2008}, month = {May}, publisher = {ACM}, isbn = {978-1-60588-157-6}, }
