Abstract

Distributed Real-time Embedded (DRE) middleware which is based on OMG Real-time CORBA standards is increasingly being used to develop highly distributed application which have stringent real-time QoS requirements.

With the introduction of middleware based on the CORBA Component Model (CCM) standard, DRE developers will be able to develop component-based distributed applications which will be easier to model and assemble using higher level modeling tools.

However, CCM does not address some of the more complicated QoS Management issues associated with developing Real-time applications. QoS management is a cross-cutting concern which spans many component, system, and application-level boundaries.

In this presentation, we introduce some ideas for how some of the QoS Management concepts in the BBN Quality Objects (QuO) framework can be used to augment CCM with dynamic QoS management capability.
