适用于软件无线电分布式环境的CORBA中间件性能分析

Performance Analysis of Corba Middleware for Software-Defined Radio Distributed Environment

随着越来越多的人研究软件无线电通信,公用对象请求代理体系(Common Object Request Broker Architecture,CORBA)中间件在软件无线电通信领域的应用也变得越来越广泛,在软件无线电平台上选择一款合适的中间件则变得越来越重要。中间件既要保证能够满足传输时延的要求,又需要在传输数据时抖动小。在相同的硬件测试环境下,通过运用控制变量法,测试使用TAO、omniORB、e*ORB这3种中间件时的平均传输时延、传输时延抖动、吞吐量3个性能指标,为选择合适的中间件提供数据支撑。

As more and more people study software radio communication,the applications of CORBA(Common Object Request Broker Architecture)middleware in the field of software radio communication become more and more extensive.It becomes more and more important to choose a suitable middleware on the software radio platform.It is not only necessary to ensure that the middleware can meet the requirements of transmission delay,but also needs to have small delay jitter during transmission.Under the same hardware test environment,this paper uses the control variable method to test the three performance indicators of average transmission delay,transmission delay jitter,and throughput when using TAO,omniORB,and e*ORB,and provides data support for selecting appropriate middleware.
