Scheduling methods of virtual machine (VM) migration are regarded as an effective way for energy conservation. A number of scheduling methods of VM migration have been proposed and/or improved in several research works. However, none of the scheduling methods was evaluated from a comprehensive viewpoint, and there is no useful reference for practices of energy conservation in various data centers...
Recently, peer-to-peer (P2P) networking has been proposed to deliver contents efficiently in Distributed Virtual Environments (DVEs) without overloading servers. Due to the nature of the real-time communications in DVEs, peers should carefully select neighbors and content pieces with prioritization in order to achieve the best streaming quality. In this paper, we proposed a prioritization framework...
Live data migration is an important technique for key-value stores. However, due to the stateful feature, new virtualization technology, stringent low latency requirements and unexpected workload changes, key-value stores deployed in cloud environment have to face new challenges for data migration: effects of VM interference, and the need to trade off between the two ingredients of migration cost,...
As the popularity of WebVR applications rises in recent years, a great disparity exists between the huge 3D content on servers and the limited cache capacity on clients. In order to alleviate server loading, peer-to-peer (P2P)-based 3D content distribution has been proposed recently. However, given the limited cache sizes at clients, how to maintain and replace the cache content effectively becomes...
Wireless equipped machines are increasing greatly in recent years, among which the cellular network based machine-to-machine communication (M2M) has shown the advantages of better coverage and lower network deployment cost. However, the current cellular network is designed for human-to-human communication, targeting the voice/media transmission with low access delay and high throughput, so the machines...
Now all kinds of 3D virtual worlds have been popular on Internet, but due to gigantic data of virtual scenes and limit network bandwidth, traditional Client/Server based downloading scheme has been bottleneck for a user to construct local virtual worlds swiftly. This paper proposes a parallel delivery scheme for large scale virtual scenes in a two-layer hybrid based P2P(Peer-to-Peer) overlay, in which...
