The abstract follows.
> Paper Abstract:
> Recent proposals for network virtualization provide a promising way to
> overcome the Internet ossification. The key idea of network
> virtualization is to build a diversified Internet to support a variety
> of network services and architectures through a shared substrate. A
> major challenge in network virtualization is the assigning of
> substrate resources to virtual networks (VN) efficiently and
> on-demand. This paper focuses on two versions of the VN assignment
> problem: VN assignment without reconfiguration (VNA-I) and VN
> assignment with reconfiguration (VNAII).
> For the VNA-I problem, we develop a basic scheme as a building block
> for all other advanced algorithms. Subdividing heuristics and adaptive
> optimization strategies are then presented to further improve the
> performance. For the VNA-II problem, we develop a selective VN
> reconfiguration scheme that prioritizes the reconfiguration of the
> most critical VNs. Extensive simulation experiments demonstrate that
> the proposed algorithms can achieve good performance under a wide
> range of network conditions.
