摘要： 基于软件性能模型的软件性能评估可以应用在软件研发周期的早期阶段，以便对软件系统的行为进行定量分析。该文给出一种应用排队网络模型对VoIP信令解析软件体系结构性能的评估方法。该方法的基本思想是：从基于UML描述的活动图导出多类排队网络性能模型，通过统计分析将得出的性能参数反馈给UML软件体系结构模型，不断完善体系结构设计。模型提供的统计性能评估方法克服了受限估计离散事件分析的局限性。

Abstract: The evaluation of software performance based on performance models can be applied at early phases of the software development cycle to characterize the quantitative behavior of software systems. This paper presents an analytical method based on queuing networks models for VoIP signaling parse module for the performance of software architectures. Starting from annotated UML activity diagrams, a performance model based on multi-class queuing networks is derived and statistic analysis is made. Performance results are reported back to the software architecture model in the UML diagrams, and can be used to instruct architectural design. This model provides a statistical performance evaluating method, which overcomes the limitations in bounding calculations and discrete event analysis.

Key words: signaling parse, UML activity diagrams, multi-class queuing networks, performance evaluation
