天线交换柜系统网络性能的测试评估

在嵌入式天线交换柜系统设计过程中,由于资源有限,不能无限制的增强系统的处理能力,又不能使系统的吞吐率太低,使应用程序无法正常运转,系统性能与资源使用率如何最佳配置是一个问题。本文根据排队论中的开环排队网络模型,将嵌入式天线交换柜系统抽象为一个排队服务系统,而将网络上到达的数据作为顾客,这些顾客的到来是符合一定的概率分布的,这样就可以根据系统要达到的性能推算出系统资源的配置方案,同时也可以确定系统相应的目标参量,根据这个方案来分配系统资源可以达到性能和资源最优组合。

Testing and evaluation of network capability in the embedded antenna switching system

In the design procedure of embedded antenna switching system because of limited resource it is difficult to enhance theperformance of system.But the application request must be satisfied.How to arrange the system resource is a problem.A new methodbased on queue theory is presented in this paper.Embedded antenna switching system can be viewed as a queue system.The datafrom Internet been seen as the customers and all these customers according with a given statistical order.Based on this queue modelthe best optimize performance can be reached.Specially, target performance parameter also can be given out.
