Through virtualization, multiple virtual machines (VMs) can coexist and operate on one physical machine. When virtual machines compete for memory, the performances of applications deteriorate, especially those of memory-intensive applications. In this study, we aim to optimize memory control techniques using a balloon driver for server consolidation. Our contribution is three-fold: (1) We design and...
The rapid development of Video On Demand (VoD) service especially in wireless network incurs huge bandwidth costs. To reduce the bandwidth pressure and improve the user experience, Wireless Service Providers (WSP) began deploy cache in the Mobile Switching Center (MSC) following the power law distribution observation of video popularity for the whole system. However, based on the Sina Video dataset...
The multi-level storage architecture has been widely adopted in servers and data centers. However, while prefetching has been shown as a crucial technique to exploit the sequentiality in accesses common for such systems and hide the increasing relative cost of disk I/O, existing multi-level storage studies have focused mostly on cache replacement strategies. In this paper, we show that prefetching...
With the increasing amount of distributed computing systems applied in wide range of critical domains, the requirement of high reliability and high availability of distributed computing systems tend to more and more urgent, that the study of distributed fault-tolerant system become more significance. This paper provides a model of triple-modular redundancy dynamic fault-tolerant system, and the reliability...
