【摘要】 网络系统集成广泛应用在企业、政府中,承载着大量的信息,随着计算机技术的发展,特别是近年来,网络、存储等相关技术取得了突破性的进展,使得如今的网络系统集成平台越来越复杂,功能也越来越强大。然而正是由于网络系统集成复杂度和功能的提高,网络系统集成可用性问题日益突出。 本文在研究传统可用性的定义、评价方法和相关指标体系的基础上,针对网络系统集成的可用性的特点进行分析并对其范围进行了界定,确定网络系统集成可用性的主要参数,并且根据这些参数对网络系统集成的可用性从宏观和微观两个角度进行分析,给出了所有指标的量化计算方法。对原有方法进行扩展,结合各种方法的优点,提出对网络系统集成可用性的建模和分析方法。并且根据应用环境的不同需求对可用性进行等级划分。最后通过实例说明了该方法在实际应用中的可行性和有效性,为网络系统集成可用性的定性定量分析评价提供了一种新方法。更多还原

【Abstract】 Network system integration has been widely applied in enterprises and government to withhold massive information. With the development of computer technology, network, storage and other relevant technologies have achieved breakthrough improvements in recent years. As network system integration becomes more and more intricate and complex, the issues and concerns for availability of network system integration have also become more apparent.After studying the conception and features of traditional availability ,this article aims to analyze the features of network system availability, and to determine the main parameters of integrate system availability, and to analyze from both macro and micro perspectives in accordance to such parameters, and to generate an index for all quantitative formulas. If further examines conventional availability and estimation methods. This article attempts to extend from original methods and integrate advantages of various methods to analyze and design a model network integration system. Furthermore, it will also rank the availability of network system with relevance to different circumstances and demands. It will prove its practicality, and effectiveness through applied examples, as to provide a quantitative and qualitative analysis for network system integration availability.更多还原
