摘要:

针对Web Service与网关特点,将基于Web service的电信网关与基本业务网络考虑为一个整体进行建模,给出了具有有限源和基于会话特点的闭环排队网络模型及M/G/1/K/H PS(C)排队模型。模型可用于系统瓶颈确定、性能预测和应用程序配置等方面。另外,对实际电信网关系统进行测量,分析了模型的应用及配置参数对系统性能的影响,实验结果证实了模型的有效性。

关键词: 性能分析, 排队理论, 基于Web Service的电信网关

Abstract:

Analytically modeling the behavior of Web service based telecomm gateway is investigated. A model based on a closed queuing network was proposed. In such a proportion there include several characteristics such as finite-sources, multi-classes services and session-based requests. Further, an M/G/1/K/H PS(C) queue model was used to simplify it. The model could be used in system bottleneck identification, performance prediction, and application configuration and some metrics are evaluated for improving the performance of the system. A Web service based telecom gateway was implemented in our project, and experimental results indicate that models faithfully capture the performance of the gateway.

Key words: performance analysis, queuing theory, telecomm gateway
