Workshop on Overlay and Network Virtualization, March 6, 2009In conjunction with the 16th GI/ITG Conference on Kommunikation in Verteilten Systemen (KiVS 2009), Kassel, Germany, March 2-6, 2009See here for the workshop program. See here for travel information to the KiVS workshop. Call for papers Recently, several “Future Internet” initiatives
have started in Europe, the US and Asia, offering the exciting opportunity to
design new approaches to supporting richer network services in a variety of
scenarios and environments, such as middleboxes, IPv4-v6 interworking, p2p, and
other services. These research efforts may eventually lead to an internetwork
architecture with the support of overlay and network virtualization
significantly more flexible features than the traditional Internet. The workshop welcomes submissions from both
researchers and practitioners that explore recent investigation on
architectural and design issues as well as related implementation,
experimentation or simulation efforts towards realization of overlay and
network virtualization for the future internetworks. Original papers not under consideration of another conference, workshop or journal are encouraged to submit via http://edas.info/newPaper.php?c=6644. Submissions should be written in English, adhere to the IEEE double-column format, no smaller than 10pt size, and no more than 6 pages in total. The post-workshop version of selected papers and presentations are planned for publications in a journal special issue which will be announced in a later date. Important dates: Submission of papers: October 27, 2008 (extended; final) Notification of acceptance: November 30, 2008 Camera ready version due: December 27, 2008 Workshop date: March 6, 2009 (Friday) Workshop organizers: Xiaoming Fu (U

Vienna) Klaus Wehrle (RWTH Aachen) Lars Wolf (TU Braunschweig) Preliminary Technical Program: Keynote speaker: Title: Overlays can do more ... if not everything Abstract: Application-layer peer-to-peer overlay networks have shown to be a
disruptive technology. The ability to create large networks on-the-fly
has enabled new application services in support of content distribution,
file sharing, video streaming, and interactive teleconferences. But
could the role of self-organizing overlay networks be even greater? Is
it conceivable that peer network protocols become the foundation for a
new architecture that is entirely based on the concepts of
self-organizing overlays networks? Can peer network protocols evolve
into a follow-on technology to the Internet protocols? We claim that
potential and fundamental limits of the peer networking approach remain
largely unexplored. We envision a network architecture characterized by
the coexistence of virtually unlimited numbers of peer networks that can
quickly grow to arbitrarily large sizes and adapt to changes in the
number of peers and substrate networks. Using applications that we built
in recent years, including a situation awareness system for emergency
responders, a video streaming in mobile ad-hoc networks and others, we
make the case that the overlay networking approach is vastly superior in
situations with unknown, uncertain, and changing requirements for
information access. We report on our efforts on putting overlay
networking closer to the hardware, and discuss the challenges of running
overlay protocols directly on mobile devices, access points, and packet
switches.
Biography: Jörg Liebeherr received the Ph.D. degree in Computer Science from the Georgia Institute of Technology in 1991. He is currently with
the Department of Electrical and Computer Engineering of the University
of Toronto as the Nortel Chair of Network Architecture and Services. He
is a co-author of the textbook ``Mastering Networks: An Internet Lab
Manual, published by Addison-Wesley in 2004. He was elected to the Board
of Governors of the IEEE Communications Society for 2003-2005, and chair
of the IEEE Communications Society Technical Committee on Computer
Communications in 2004-2005. He was Editor-in-Chief of IEEE Network in
1999-2000, and an Associate Editor of IEEE/ACM Transactions on Networking and several other journals. He received an NSF Career award
in 1996, a Virginia Engineering Foundation fellowship in 2002, a best
paper award (as co-author) at ACM Sigmetrics 2005, and an Outstanding
Service award from the IEEE ComSoc Technical Committee on Computer Communications in 2006. He is a Fellow of the IEEE. His current research interests are networks with service guarantees and self-organizing peer networks.
