Joint scheduling of both computation and communication resources for workflow based distributed computing application over optical networks has been studied recently. Most algorithms proposed in previous work are mainly based on static scheduling strategies with assumption that detail resource information and accurate performance prediction is available. In this paper, we propose to employ shared...
We propose a framework of data center consolidation with virtual private network and discuss the benefits and challenges of the proposed framework. After reviewing related background such as cloud computing and virtual private network, a preliminary case study in food industry by using our proposed framework is present to validate our idea. We believe that it paves the way to the future enterprise...
Recent studies on overlay networks have shown that non-default paths can provide dramatically large performance benefits compared to default ones. In the present paper, we propose a dynamic overlay routing mechanism which chooses paths based on a composite metric determined by actively probed delay and jitter information in a real-time fashion. The effectiveness of this mechanism is examined under...
