Paper Abstract:
|
In the last years, multimedia applications have been evolving and taking an important role in the multi-domain information exchange on the Internet. Although the QoS parameters required by the multimedia applications are well known and some form of guaranteed QoS is available at transport and network layers, there is no standard QoS specification enabling to deploy the underlying mechanisms in accordance with the application QoS needs. This paper introduces a global XML-based QoS specification language, called XQoS enabling to supply a complete description of applications QoS needs that can be easily mapped towards transport, network and system QoS oriented services. An experiment illustrates how XQoS can be used for configuring dynamically the communication subsystem in order to satisfy audio and video on demand QoS requirements. |
