IUCG preliminary consideration
The considered technologies corresponds to usage concepts such as:
- externets: external shared networks lookalike within the network.
- SN/HN: small network, home network, stand alone host.
- interapplication layer.
- ONES: Open Network Extended Systems: plugged into the Internet edges via OPES (Open Pluggable Edge Services)
Topic
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. These new performance aspects may comprise the quality of isolation, fairness among virtual systems, the location transparency of virtual services, the quality of synthetic virtual resources, and the scalability of the composition of virtual network and service and of the management mechanisms for virtual network and their communication patterns. As a follow-up of the successful 20th ITC Specialist Seminar on Network Virtualization (Hoi An, Vietnam, 20.-21. May 2009), the objective of this special issue of the IJCNDS is to 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
Performance issues of virtualization techniques on routers and end hosts
- Isolation and fairness for the resource access among multiple guest systems on a single host
- Performance issues of virtualized operating systems and server virtualization
