摘要HETHIS论文对虚拟化的软件复兴进行了短暂分析。特别是，我们应用相型扩展来分析基于虚拟机软件（VM）的软件复兴的点可用性，并使用两个策略分析。冷VM和温暖的VM恢复政策。性能度量可以源自由标记的马尔可夫再生随机培养皿网（MRSPN）描述的随机模型。
Abstract HeThis paper presents a transient analysis of software rejuvenation with virtualization. In particular, we apply the phase-type expansion to analyze the pointwise availability of virtual-machine (VM) based software rejuvenation with two policies; cold-VM and warm-VM rejuvenation policies. The performance measures can be derived from the stochastic models described by labeled Markov regenerative stochastic Petri Nets (MRSPNs).
