Service Selection Model for Multimedia Service Workflow

摘要：

Under SOA, QoS is one important factor of service selection for workflow. A wide range of attributes such as availability, reliability, performance, and reputation have been chosen to be criterions for QoS. However, in the domain of multimedia service, it has its unique characters, which might not be described and satisfied by generic QoS model. For example, video streaming does not need to get the fastest delivery network but has well-defined requirements in its data rate. In this paper, we introduce a novel model to help multimedia service selection. Both the theory behind and its simulation study are presented. Our results show that quality requirement is a good guidance for multimedia service selection.
