摘要: 针对跨域资源调度过程中不同域之间信任度评价差异,域与域之间实体信任度无法比较的现象,提出了一个域间信任度计算模型,并由域代理完成不同信任机制的相互转换。通过对不同域之间资源调度历史记录以及推荐信任度进行综合评价,把域间信任度进行规范化,使域之间的信任度有了可比性;给出了跨域信任体系结构;提出了实现跨域调度的算法。实验表明,提出的信任模型和调度算法在跨域范围内选择了信任度高的资源,提高了任务满足率和调度成功率。

关键词: 域间信任, 体系结构, 调度算法

Abstract: The establishment of trust relationship inter-domain is difficulty due to the difference of inner-model of trust domain, consequently,the entity trust value is difficult to compare in inter-domain scheduling.This paper proposes a new inter-domain trust model which consists of between-domain trust and inner-domain trust,and implements with domain agent infrastructure.In order to make it comparable,it is to standardize the different records of domains,as well as recommend the resource scheduling of a comprehensive evaluation of trust in the inter-domain trust standardized;give the trust structure of inter-domain;put forward the scheduling algorithms of inter-domain.Experiments show that the proposed trust model and scheduling algorithm in the framework of inter-domain trust choose high resources,improve scheduling tasks to meet the rate and success rate.

Key words: inter-domain trust, architecture, scheduling algorithm
