Abstract

Maintaining end-to-end quality of service (QoS) is a challenge in distributed realtime embedded systems due to dynamically changing network environments and resource requirements. The authors' middleware QoS management approach encapsulates QoS behaviors as software components. Using the Corba Component Model, they build these specialized QoS components and combine them to produce a comprehensive management system that maintains QoS. The authors illustrate their approach by building a real-world medium-scale system with these components. Using this example, they demonstrate the reusability of each component in different contexts.
