Network virtualization is the technology that allows the simultaneous operation of multiple logical networks (also known as overlays) on a single physical platform. Network virtualization permits distributed participants to create almost instantly their own network with application-specific naming, routing, and resource management mechanisms such as server virtualization enables users to use even a whole computing center arbitrarily as their own personal computer. Recently, network virtualization received tremendous attention since it is expected to be one of the major paradigms for the future Internet as proposed by numerous international initiatives on future networks, e.g. PlanetLab (USA, International), GENI (USA), AKARI (JAPAN), OneLab2 (Europe), and G-Lab (Germany).

Network virtualization is a rather new technology with performance aspects not yet eminent but expected to grow with its spreading application, the scaling of this new type of virtual networks, and the dynamics of invoking them. An example of a major performance issue in network virtualization can be motivated as follows. In server virtualization, the performance of the guest system ideally does not depend on the location of guest in the host.s memory, respectively on the location of the host.s resources. This feature can be defined as memory invariance. Similar to this characteristic, a virtualized network should reveal also an invariance feature for performance. The performance or the one of the services provided by the virtual system should be independent on the location of the mechanisms, its implementation, or even on the location of the entities providing the virtual service.

A major objective of this ITC Specialist Seminar is to identify early and future performance issues and to provide methodologies and mechanisms to address the various aspects of performance in network virtualization. The seminar is intended as a forum for scientists and engineers in academia and industry to exchange and discuss their latest experiences, and research results. It will address techniques, architectures, performance models, and performance engineering methods leading to real world network virtualization solutions that provide users with efficient techniques for creating and operating their own high performance virtual network.

Topics of interest are amongst others, but not limited to:
