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)

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.
