迁移工作流系统中的迁移域组织与动态迁移实例寻址研究

该文将安全性和高效性原则应用到迁移工作流的迁移决策中。首先,用确定静态迁移域的方法来保证迁移实例不会迁移到恶意工作位置中。然后在迁移域的范围内,对各工作位置进行信任评价,使迁移实例迁移到满足其工作流服务要求的最佳的工作位置中运行,保证了系统运行的高效性。该文讨论了迁移实例的迁移决策问题,包括对静态迁移域的组织,迁移域中工作位置的可量化的信任关系评价,以及基于信任评价的动态迁移寻址。

The Migrating Domain Organizing and Migrating Instance Seek Work Position Research in Migrating Workflow System

The thesis applies the security and efficiency rule to the migrating decision in migrating workflow.Firstly,the method of organizating migrating domain assures the migrating instance never migrating to the danger workpositon.Secondly,in the scope of migrating domain,each workpostion is evaluated by the trust,so migrating instance will migrate to the best position to run and the system are assured efficiently.The thesis discusses the migrating decision of migrating instance,including the organization of static migrating domain,workposition's trust evaluation,and the dynamic seeking aim on the basis of trust.
