We describe in this paper a component for supporting Quality of Service (QoS) in object environments. This component, called the micro QoS manager (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 co-operation of the 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.This paper focuses on the micro QoS manager, and gives an overview of its implementation in a CORBA platform in the context of a video on demand application.
