An Infrastructure for Dynamic Composition of Grid Services

This poster presented Rudder, an agent-based infrastructure for the dynamic composition of gid services. Rudder is based on an associative composition space abstraction, and supports dynamic workflow enactment using software agents. The agents semantically discover and select services required by the workflow, and compose the selected services. The agents manage the execution of the workflow at runtime, and adapt the workflow reactively. Prototypes of Rudder and the Comet substrate have been developed and deployed as Java services within the JXTA framework
