The widespread use of distributed multimedia applications is posing new challenges in the management of resources for guaranteeing Quality of Service (QoS). For applications relying on the transfer of multimedia information, and in particular continuous media, it is essential that QoS is guaranteed at any level of the distributed system, including the operating system, the transport protocol, and the underlying network. Enhanced protocol support for end-to-end QoS negotiation, renegotiation, and indication of QoS degradation is also required. Little attention, however, has so far been paid to the definition of a coherent framework that incorporates QoS interfaces, management and mechanisms across all the layers of a management architecture. This paper describes a preliminary study in the development of an integrated Quality of Service Management Architecture (QoSMA) which offers a framework to specify and manage the required performance properties of multimedia applications over heterogeneous distributed systems.
