An experimental service composition tool for media-centric networked applications

In order to explore diverse types of media-centric service composition in real environments, we have built a service-oriented testbed named as FIRST@PC (Future Internet Research on Sustainable Testbed based on PC). FIRST@PC targets a flexible and cost-effective testing environment where media-centric service compositions are flexibly realized on top of computing/networking resources. In this paper we design and implement an OMX (Open Media eXperiment for service composition) experiment control tool to support media-centric service composition. By following the SOC (service-oriented computing) paradigm, the OMX tool assists experimenters to flexibly integrate computing and networking services. To explore the possibility of media-centric service composition, we also prototype the FIRST@PC testbed consisting of multimedia computing and networking devices. The implemented OMX tool is verified by an HD media service composition scenario run on this prototyped testbed.
