Computer science description: The explicit management of Quality of Service (QoS) of network connectivity, such as, e.g., working cost, transaction support, and security, is a key requirement for the development of the novel wide area network applications. In this paper, we introduce a foundational model for specification of QoS attributes at application level. The model handles QoS attributes as semantic constraints within a graphical calculus for mobility. In our approach QoS attributes are related to the programming abstractions and are exploited to select, configure and dynamically modify the underlying system oriented QoS mechanisms. publisher: Springer contributor: Dershowitz, Nachum date: 2004 type: Book Section type: PeerReviewed identifier: De Nicola, Rocco and Ferrari, GianLuigi and Montanari, Ugo and Pugliese, Rosario and Tuosto, Emilio A Formal Basis for Reasoning on Programmable QoS.
