We present a network I/O allocation framework, called Raccoon, for workload-aware VM scheduling algorithm to facilitate hybrid I/O workloads in virtual environments. Raccoon combines the strengths of paravirtual I/O and SR-IOV techniques to not only minimize the network latency, but also optimize the bandwidth utilization for workload-aware VM scheduling. In Raccoon, a limited number of VFs in SR-IOV...
With the growth of cloud computing and other high-bitrate disaster recovery center (DRC) support service, DRC networks play an important role in the future networks. But the nature or man-made disaster is the main threaten of survivability. In this paper, we focus on the protection of DRC node based on contentconnectivity against disaster in disaster recovery center networks. An integer linear programming...
Network virtualization is regarded as a promising solution to the revolution of the current Internet. With virtualization, disruptive technologies can be easily deployed over the logic (service) network and transparently mapped to the physical network via the network embedding process. In this work, we address the survivability issue in the virtualization context via resolving the survivable network...
