This paper presents a Quality of Services (QoS) control mechanism for distributed multimedia computing, and describes the design and implementation of this mechanism, which is based on the RSVP protocol. The purpose of this QoS control mechanism is to provide end users with customized computations according to the QoS demands for effective utilization of network resources. The mechanism establishes, maintains, and deletes end-to-end sessions for different multimedia streams and provides both guaranteed service and controlled load service to end users in perceptual-time, but not real time. We discuss the key components of the QoS control mechanism, such as the architecture of the mechanism, the mathematical definitions of QoS parameters, the implementation formats of the control packets based on the defined QoS parameters and RSVP, and the packet scheduling policy in routers. This paper describes the implementation of a prototyping system for QoS control based on the proposed control mechanism.
