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
