摘要
该文建立了独立智能外设的多任务类型封闭排队网络模型。对独立智能外设上开展的彩铃业务进行了分析,并使用近似平均值分析(MVA)算法求解出了系统的相关性能指标。通过分析这些性能指标,可以找到制约系统性能的瓶颈。最后,用OPNET进行了仿真,验证了分析的有效性。
Aiming at the analysis for the service performance of independent intelligent peripheral, this paper presents the performance model based on queueing network. With the analysis of the service features and the basic information flow of the CRBT (Color Ring Back Tone) service deployed on the independent intelligent peripheral, Some performance metrics are obtained through using the approximate Mean Value Analysis(MVA) algorithm. These metrics help to find the bottleneck of the system and improve the quality of service. Finally, OPNET is used to simulate the system, and verified the accuracy of this model.
