实时CORBA技术研究及性能分析

下一代网络业务提供是一个分布式系统,在支持通信类增值业务时要求一定的QoS保证。实时CORBA采用面向对象的方法,提高了分布式应用软件的可重用性和可扩展性,大大简化了分布式应用系统的开发和维护,便于异构环境下的系统集成;而且为分布实时应用提供端到端的可预测性。结合实时CORBA规范及其产品中的实现技术,讨论了实时CORBA的资源控制策略及其实现的协议框架,并用试验分析验证它的实时性能。实时CORBA改善了通用CORBA的实时性能,能够为下一代网络业务提供一定的实时保证。

Research on Real-time CORBA and its Performance

Next Generation Network (NGN) service platform is a distributed system and must ensure quality of service supportfor value-added service in communication. Real-time CORBA adopts object-oriented methods to enhance the reusabilityand extensibility of distributed application software, which largely simplifies the development and maintenance ofdistributed application system and makes the system integration easy in heterogeneous environment. Furthermore itprovides the end-to-end predictability in distributed real-time application. Following the discussion of the resourcecontrol strategies and the protocols framework in implementation based on real-time CORBA specifications and theimplementation technologies of its products, the results of experiments verify its performance. Real-time CORBAimproves the real-time performance of general CORBA, hence, it can provide quality of service when applied in NGNservice.
