Venkatasubramanian, N. and Agha, G. and Talcott, C. L. - 2004

In this paper we present a meta-architectural framework for customizable QoS-based middleware based on the actor model of concurrent active objects. Using TLAM, a semantic model for specifying and reasoning about components of open distributed systems, we show how a QoS brokerage service can be used to coordinate multimedia resource management services in a safe, flexible and efficient manner. In particular, we show that a system in which the multimedia actor behaviors satisfy the specified requirements, provides the required multimedia service. The behavior specification leaves open the possibility of a variety of algorithms for resource management as well as adding additional resource management activities by providing constraints to ensure their non-interference.
