为了将具有关键业务任务的用户吸引到网格，他们必须信任所请求服务的可靠性。服务水平协议（sla）已经成为以契约方式定义作业执行的服务质量（QoS）的第一种方法。然而，在网格世界中，sla并没有真正被接受，因为资源提供者对它们持谨慎态度，而用户对接受协商好的QoS也没有信心。AssessGrid项目提供了一些概念，通过发布sla失败的概率来帮助提供商获得用户的信任，一旦清楚地说明了这些概率，就会增加用户的信心。用户可以将此信息用作SLA协商过程中的决策因素。本文提出了通过在网格层中集成风险意识来增加对SLA供应的信任的AssessGrid思想。由于只有可靠的信息才能建立信任，因此在AssessGrid中正在开发对提供者可信性的公正评估。
In order to attract users with business-critical jobs to the Grid, they must trust the reliability of the services they request. Service Level Agreements (SLAs) have been a first approach to contractually define the Quality of Service (QoS) for a job execution. However, SLAs are not really accepted in the Grid world since resource providers are cautious agreeing them, and users not confident receiving the negotiated QoS. The AssessGrid project offers concepts to help providers gain the users’ trust by publishing the probability of failure of SLAs, leading to an increase of users’ confidence once these probabilities are clearly stated. Users can use this information as a decision factor in the SLA negotiation process. This paper presents the idea of AssessGrid in the scope of increasing trust in the SLA provisioning by integrating risk awareness in the Grid layers. Since only reliable information can create trust, an impartial evaluation of the provider’s trustworthiness is being developed in AssessGrid.
