针对传统中介器/包装器(mediator/wrapper)结构上的安全问题,提出了一个多中介器的安全信息集成模型.该模型采用多中介器协作技术,根据当前系统的状态和各中介器本身的性能,以最少等待时间为调度原则,动态选举最优的中介器完成查询任务.该模型既可保证系统的安全性,又可提高系统的效率.
Aimed to improve the secure performance of traditional mediator / wrapper architecture,it was proposed an information integration model with multi-mediator. Adopting multi-mediator collaboration technology,the model could dynamically elect a mediator to deal with the query according to status and performance of mediators and least-wait-time policy,so that the model was not only secure,but also efficient.
