CORBA application tailored manager for quality of service support

We describe a component for supporting quality of service (QoS) in object environments. This component, called the micro QoS manager (μQoS-Mngr), is associated to an application and handles all aspects of static and dynamic QoS management related to that application. End to end QoS management is provided through the cooperation of the μQoS-Mngr with a set of object resource managers (OR-Mngr) each of which is responsible for the QoS management of a specific resource, including, admission control, real-time scheduling and monitoring functionalities. QoS renegotiation is achieved through application process monitoring and communication, with the OR-Mngr. We focus on the micro QoS manager and give an overview of its implementation in a CORBA platform in the context of a video on demand application
