Abstract

This chapter addresses the task of building Internet-based service provisioning systems where the quality of services (QoS) provided should not be perturbed due to changes in execution environments and user requirements. Specifically, it presents a system architecture and identifies a model appropriate for developing distributed programs that would implement the system. The model abstracts the network performance and dependability guarantees typically offered by the Internet service providers and is termed the probabilistic asynchronous model. The protocols for this model are shown to be derivable from those developed for the well-known classical models, namely: the synchronous and the asynchronous models. A protocol for reliable broadcast is derived from a synchronous protocol, together with QoS management algorithms. The system architecture prescribes the role of QoS management algorithms to be: feasibility evaluation on QoS requests from the end users, and adapting system protocols in response to changes in the environments. © Springer-Verlag Berlin Heidelberg 2004.
