Providing end-to-end QoS assurances in a CORBA-based system

Unlike other real-time CORBA implementations that focus on real-time support for simple client-server applications, our ERD...

Description
Summary:In this paper we describe the implementation of our end-to-end QoS-driven resource management scheme, called ERDoS, within a CORBA-compliant ORB that we call the ERDoS QoS ORB. Unlike other real-time CORBA implementations that focus on real-time support for simple client-server applications, our ERDoS QoS ORB provides end-to-end QoS support (i.e., QoS spanning computer network, and storage resources) to applications, while retaining the benefits of an open distributed object system. Specifically we present three contributions. First, we present a model for describing end-to-end applications as a combination of client-server interactions between CORBA objects. Second, we define a model for relating the user/application level QoS requirements to the corresponding resource demand requirements of these individual CORBA objects. Third, we suggest a framework for performing distributed resource management within the CORBA environment.
