With the booming trend of cloud computing, on-demand resource management is overwhelming static and dedicated strategy. The increasing demands introduce multiple challenges including energy efficiency, performance enhancement, and fault tolerance. Virtualized computing environment decouples OS and applications with hardware to best facilitate these on-demand cloud services. In this paper, we propose...
In largely distributed clusters, computing nodes are geographically deployed in various computing sites. Information processed in a distributed cluster is shared among a group of distributed processes or users by virtue of messages passing protocols (e.g. message passing interface - MPI) running on the Internet. Because of the open accessible nature of the Internet, data encryption for these large-scale...
A network deployment of generally available operating systems (OS) usually takes in the order of tens of minutes. This is prohibitive in an environment in which OSs must be dynamically and frequently provisioned in response to external requests. By exploiting the fact that in general only a small part of an OS image is actually required to be present to perform useful tasks, we demonstrate how an...
The ossification of Internet infrastructure and protocols have hindered the advancement of itself. GENI, AKARI and several other similar initiatives are pushing forward to overcome this hindrance. They facilitate researchers with networking platforms dedicated for innovative networking experiments. In these virtualized platforms, researchers can define their own forwarding schemes which can be radically...
