【摘要】 本文采用流体流近似法分析了采用数字语音插空(DSI)技术的电路/分组混合交换系统的性能。这种方法基于话音业务和数据业务的不同统计特点,可以近似求得系统中数据排队的概率分布函数。本文还引入了描述话音过程的二维马氏链模型,这个模型可以用于一般的采用话音插空技术的系统性能分析。更多还原

【Abstract】 In this paper, the fluid-flow approximate method is used to analyse performance "of circuit/ packet hybrid switched systems with digital speech interpolation (DSI) technique. The queueing distribution function of data traffic in the system can be derived from the method based on the distinquished statistical characteristics between voice traffic and data traffic. This paper introduces a two-dimension Markov chain model for voice process which can be used to analyse performance of generic systems with DSI technique.更多还原
