CORBA分布计算平台基于反应式Agent模型的流控机制研究

RESEARCH ON STREAM CONTROL IN CORBA PLATFORMS BASED ON REACTIVE AGENT MODEL

基于反应式 Agent模型和 CORBA标准中 POA处理状态语义的定义 ,提出了一种基于层次管理域的可配置多端口 ORB结构 ,支持用户按照管理域部署和管理分布应用 ,并基于该结构讨论了 CORBA分布计算平台的流控实现技术 .基于 Reactor模板的扩展技术 ,给出了一种基于事件类型“借用”策略 ,公平、自调度的流控机制和算法 。

A kind of ORB core structure is provided in this paper, which makes application developers deploy their distributed applications according to management domains and provides a different network port for each management domain, through analyzing the roles in ORB core based on the reactive agent model and the semantics definition of processing states of POA in CORBA specification. Based on the structure above, the techniques to implement the stream control in CORBA platforms are discussed. Moreover, the mechanism and algorithm of the stream control that can fairly schedule requests to execute by itself are designed, which can resolve the key problems in the stream control in CORBA platforms.
