摘要
针对策略管理系统中事件的处理机制,首先给出了基于事件的策略管理模型,采用注册和订购的方式进行事件收集,由PDP实现事件的合成和不同域之间的事件中转,以尽量减少传播的事件数目,防止事件风暴的发生;然后给出了基于事件树的事件合成算法,用于解决事件乱序和事件覆盖问题,保证事件合成的准确性,为策略管理提供可靠的保障.
The event processing mechanism in policy management system presented first a events-based policy management model, in which the event collection was performed by means of registering and purchase ordering, the event composition and transfer across different domains was implemented by PDP. These approaches could decrease event-transmits greatly so as to avoid the event-storm. Subsequently, an event-tree algorithm was given to solve the event disorder and event overlapping problems. By doing so, events could be composed correctly and reliable policy management could be guaranteed.
