Distributed multimedia applications would be a useful tool in the manufacturing industry. They are typically time-based applications which impose several time related constraints on communication systems. Quality of Service (QoS) parameters are necessary to describe the requirements to transfer multimedia information in communication systems. The international standard Manufacturing Message Specification (MMS) is an application layer protocol which specifies services for the distributed manufacturing applications. It enables communications between heterogeneous devices, but is not suitable for multimedia applications because it does not present QoS parameters to its objects and services. This paper proposes an extension of MMS for integrating multimedia functions. The goal is to define an MMS multimedia companion standard. Like the VMD which models manufacturing devices for MMS communication, a Virtual Communication Support (VCS) is proposed to virtualize a communication system in an MMS environment. Potential uses of VCS are also discussed.
