CORBA application tailored manager for quality of service support

Abstract

We describe a component for supporting quality of service (QoS) in object environments. This component, called the micro QoS manager (/spl mu/QoS-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 /spl mu/QoS-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.
