....Metadata Management in Relational DBMS. 5 QoS MANAGERS In the framework of a research project funded by the Canadian Institute for Telecommunication Research (CITR) we study enabling technologies for distributed multimedia systems and applications such as news on demand or teleteaching systems[10]. More specifically, we focus on quality of service (QoS) negotiation and adaptation in distributed multimedia systems. We aim at proposing approaches and algorithms to satisfy QoS constraints specified by the users. The concept of Quality of Service was originally introduced in computer ....

....our view of QoS aware distributed query processing. 1. Introduction Quality of Service (QoS) management and database systems (DBS) are two key functional units that contribute to the success of emerging distributed multimedia applications, such as electronic commerce [2] or news ondemand [14]. However, these applications are not the simple combination of database and network technologies, since they require higher performance and real time constraints. These new requirements change some of the underlying assumptions and thereby pose new challenges. Among them, the integration of QoS ....

....media streams in a MBone conference. These tools are integrated into the multimedia presentational technologies developed by the Canadian Institute for Telecommunications Research, which support the retrieval of documents stored in a multimedia database and quality of service negotiation [3]. A salient feature of our design is that extended software is not required at the machine of every user who wishes to take part in a distance education session. For student machines, off the shelf versions of vic and vat are used to transmit live audio and to receive audio and video from anyone ....

....the flexibility to incorporate (a) a range of resource reservation schemes and scheduling policies, and (b) a range of new system component technologies. We are planning to implement NAFUR in the context of the CITR (Canadian Institute for Telecommunication Research) news on demand prototype [Won 97]and to quantitatively evaluate the gain obtained by using NAFUR in the context of the news on demand application. Acknowledgment This work was supported by a grant from the Canadian Institute for Telecommunication Research (CITR) under the Networks of Centres of Excellence Program of the ....

....How such a framework can be realized is described in Section 3, where a presentational multimedia application is considered which provides access to remote multimedia databases, such as News on demand. The ideas presented have been implemented in a prototype system of a News on demand application [Won 97] Page 5 2. A General Quality of Service Management Framework During the negotiation or renegotiation of the QoS parameters of an application, a system configuration should be found, if possible optimized, which provides the requested service quality at an acceptable cost. It is the task of ....

....simply relax their commitments. In the case where the new QoS requested is more restrictive than the original one, a new negotiation (Steps 2 and 3) is performed before a new configuration is established. Page 11 3. An Implementation In the context of a canadian collaborative research project [Won 97] we have designed and implemented QoS negotiation for the application of access to distributed multimedia databases, especially a news on demand demonstration prototype [Haf 96b] The system allows the user to select a multimedia (MM) document and specify his her requirements in terms of quality ....
