摘要:

为了实现综合、准确的SLA (Service Level Agreement)业务管理,对SLA参数表示及参数映射进行了研究。首先,从不同的视角定义SLA表示参数,提出双向流程分析法提取表示参数,并利用参数映射机制研究各参数之间关系,建立多视点、层次化的SLA业务管理数据模型。其次,引入层次分析方法AHP(Analytic Hierarchy Process)结合不同的判别算法对各层参数进行关联计算,完成了各层参数间的映射。最后,在UMTS网络中建立FTP业务管理数据模型并对参数映射算法进行验证。仿真结果表明了本方法的合理性和有效性。

关键词: 业务管理, 服务等级协定, 参数表示, 参数映射

Abstract:

For the purpose of implementing integrative and accurate SLA-based service management, the SLA parameter representation and parameter mapping have been studied. Firstly, SLA representation parameters have been defined from different perspectives, the analytical method of bidirectional data flow is proposed to extract representation parameters, and then parameter mapping mechanism has been adopted to study correlation among data, in this way the hierarchical SLA-based service management data model viewed from multi-perspectives is established. Secondly, Analytic Hierarchy Process (AHP) combined with other different judging arithmetic is introduced to perform correlative computing, which realizes the mapping of representation parameters among sub-layers. Finally, service management data model of FTP service over UMTS network is built and parameter mapping arithmetic is validated. The simulation results demonstrate that the proposed approach is rational and valid.

Key words: service management, Service Level Agreement, parameter representation, parameter mapping
