The most notable characteristic of continuous-media data is the existence of timing constraints. To handle such data appropriately, some system support for resource management and QOS control is indispensable. For this reason, we are proposing a `QOS-Ticket' model, which combines resource reservation and adaptation. The QOS-Ticket model has been implemented on RT-Mach. In this prototype, a new thread mechanism, named `Q-Thread,' is provided. A Q-Thread allows a user to specify the tolerable range of the period and computation time for periodic invocations, and makes it easy to write a continuous-media session that can control the QOS dynamically. We showed the effectiveness of the QOS-Ticket model based on a dynamic QOS-control experiment with our prototype.
