Practical service grid framework based on dynamic service composition
Wancheng Ni, Cims En · Computer Integrated Manufacturing Systems · 2006
In order to improve the network resource sharing and the collaboration in Practical Service Grid(PSG),the concept of Dynamic Service Composition(DSC) based framework was brought forward.By integrating simple services into one complicated service,the distributed autonomous resources could be regarded as one logical unit so that more services could be provided and Quality of Service(QoS) could also be improved.From the actual resources level to user requests level,the DSC framework was partitioned into five layers: information infrastructure layer,resource layer,basic-service layer,abstract-service layer and task layer.Each layer presented a set of implementation issues.By resolving these issues,resources collaboration could be achieved.Finally,an application example based on the DSC framework,China Equipments and Education Resource Sharing System was given.
