This paper introduces a global XML-based QoS specification language, called XQoS and an associated architecture. The design of this language is driven by the need of a global QoS description language, able to supply a complete description of applications QoS needs that can be easily mapped towards transport, network and system QoS oriented services. Moreover we propose a communication architecture that provides an efficient support to multimedia application of which the QoS needs are explicitly or implicitly expressed from the XQoS approach. This architecture allows a dynamic mapping to be done between the applicative QoS needs and the various available underlying services. An experiment illustrates how XQoS can be used for creating dynamically a protocol architecture that satisfies audio and video on demand applications QoS requirements.
