摘要

Considering the problem of estimating the financial impact of dependability improvements for commercial IP networks. An economic reliability analysis framework (called ERA) was developed at the university [2003] and applied it to a modern, commercial IP network to address the problem. The ERA framework extends traditional reliability engineering techniques to include financial elements such as: revenues, expenses, and investment periods. Full-path enumeration techniques [2003] were already extended. Markov reward models (MRM) [2003], software reliability growth models (SRGM) [2003] and stochastic reliability models [E.J. Stoker et al., 2003] using the ERA framework. This paper integrates ERA framework to reliability bounding techniques and using it to forecast the expected reliability and expected economic efficiency of a commercial IP data network. The commercial network being analyzed links 21 distinct locations along with 2 trans-oceanic edges to another IP network, each with its own collection of nodes, edges, customers and local topologies. Changes are proposed to this network to improve overall customer dependability, and the impacts of these changes (in terms of network dependability and economic return) are analyzed.

Stoker等人,2003]使用时代框架。本文将ERA框架集成到可靠性边界技术,并使用它来预测商业IP数据网络的预期可靠性和预期的经济效益。正在分析的商业网络将21个不同的位置与2个跨海边缘链接到另一个IP网络,每个IP网络都有自己的节点,边,客户和当地拓扑集合。提出对该网络来提高整体客户可靠性的变化,分析了这些变化的影响(在网络可靠性和经济回报方面)。
