UML Profiles for the Specification and Instrumentation of QoS Management Information in Distributed Object-based Applications
Juan I. Asensio, Víctor A. Villagrá, Jorge E. López de Vergara, Julio Berrocal · 2001
This paper focuses on the QoS management of IT systems based on object-oriented distributed applications. It presents a way of specifying application-level QoS information during the development of object-based distributed applications: a UML profile (an extension to the UML) based on QoS concepts and principles defined by ISO/ITU-T in their works on QoS in ODP, that can be applied to the specification of QoS management information independently of those particular details related to the distributed object-based distributed computing platform architecture used in each case. It also presents a solution (another UML profile) for modeling the instrumentation of QoS monitoring mechanisms within the monitored applications. The contributions presented in this paper are intended to facilitate the development of distributed object-based applications whose QoS can be managed in an integrated way.
