We investigate optimal rekeying interval problem in batch rekeying. A Markov model is developed for batch rekeying process. The model is then used to analyze the relationship between the rekeying interval and the batch rekeying process parameters, and a formula of the rekeying interval is presented. Simulation results show that rekeying interval decrease with the increasing rekeying rate; it increase...
Cloud computing has become a popular computing paradigm in which virtualized and scalable resources are consolidated to provide services over Internet. However, the resource capability of a single cloud is generally limited, and some applications often require various cloud centers over Internet to deliver services together. Therefore, a Virtual Organization (VO) will be a promising approach to integrate...
The network file system (NFS) protocol, as the de facto standard for sharing files in a distributed environment, has deployed Infiniband as the underlying transport of sunRPC, namely NFS over RDMA. In the current Read-Write design of NFS over RDMA, NFS write performance is limited for not fully utilizing the features of Infiniband. In this paper, we take on the challenge of enhancing the write performance...
