A Trusted Web Services Assessment Model Based on Six Dimensional QoS Framework and End-to-End Monitoring
To objectively assess quality of web services,we propose a six-dimensional QoWS framework which includes expected QoWS,agreed QoWS,delivered QoWS,perceived QoWS,transmitted QoWS,and statistic QoWS.Then a new style Web services assessment model is presented.It consists of SLA (Service Level Agreement) Register Module,Monitor Module and Assess Module.Agreed QoWS is described in SLA and declared to SLA Register.SNMP (Simple Network Management Protocol) -based Monitor respectively captures delivered QoWS,perceived QoWS,and transmitted QoWS.In a comprehensive assessment method,agreed QoWS acts as a reference point against which delivered QoWS and perceived QoWS respectively represent the relative quality of the given service deliver.Additionally,statistic QoWS is computed periodically and represents the long-term quality of the given service.
