马尔可夫调制泊松过程(MMPP)是一种随机模型,用于模拟、工作负荷表征和排队分析。本文提出了第一个用于标记MMPP(M3PP)的计数过程拟合算法,M3PP是MMPP的推广,用于模拟多种类型事件的踪迹。我们首先解释如何将两态M3PP与计数的经验痕迹相匹配。然后我们提出了一种新的合成形式,称为插入法,它使得几个两态M3PP的近似叠加而不会引起态空间爆炸。与精确叠加相比,在精确叠加中,状态空间以组合过程的数量指数增长,而在插入中,状态空间以组合M3PP的数量线性增长。实验结果表明,与人工和真实世界的轨迹相比,所提出的插补方法能够提供准确的结果,并且状态空间比叠加过程小得多。
Markov-modulated Poisson processes (MMPPs) are stochastic models for fitting empirical traces for simulation, workload characterization and queueing analysis purposes. In this paper, we develop the first counting process fitting algorithm for the marked MMPP (M3PP), a generalization of the MMPP for modeling traces with events of multiple types. We initially explain how to fit two-state M3PPs to empirical traces of counts. We then propose a novel form of composition, calledinterposition, which enables the approximate superposition of several two-state M3PPs without incurring into state space explosion. Compared to exact superposition, where the state space grows exponentially in the number of composed processes, in interposition the state space grows linearly in the number of composed M3PPs. Experimental results indicate that the proposed interposition methodology provides accurate results against artificial and real-world traces, with a significantly smaller state space than superposed processes.
