中文摘要：

开放式可重构路由交换平台以构件作为最小的物理资源，通过对不同服务的支持、装配和释放，来构建路由交换节点体系．针对可重构路由平台中的软件构件，提出了一种基于Petri网理论模型和卡尔莫格罗夫方程的可靠性理论计算方法，有效解决了可重构路由体系结构下的具有异步交互特征的软件构件和构件网的可靠性评估难题．

英文摘要：

As the smallest resources, the reconfigurable routing platform constructs routing and switching system by supporting, assembling and releasing different services. Based on software components in reconfigurable routing platforms, a method being able to calculate and assess the reliability of the system depended on Petri net is designed and implemented. This method could solve reliability access question towards the asynchronous interactive software components under reconfigurable routing system.
