摘要 对流服务的研究提出了两点改进:(1)引入服务管理及调度选择策略,全面监控、调度系统资源的使用,增强了服务质量确保能力;(2)研究CORBA安全服务和结合小波压缩的多媒体数据加密技术,提高流服务安全性并降低了加密计算复杂度。在ORBUS系统上改进了A/V流服务原型,并在网络化制造系统中加以应用。 The paper makes two contributions to the study of A/V streaming service: (1) introduces a service management mechanism for monitoring and controlling resource utilities to enhance quality of service guarantees; (2) improves the security of A/V streaming service and reduces the complexity of encryption computations by applying CORBA security services in conjunction of the wavelet compression and encryption technology for multimedia data. An improved CORBA A/V streaming service prototype is implemented based on ORBUS which is a real-time CORBA ORB, and its application in networked manufacturing system is also discussed.
