Complexity in the real-time embedded software domain has been growing rapidly. The component-based software development approach facilitates the development process of such software systems by dividing a complex system into a number of simpler components. Resource reservation techniques have been widely used for providing resources to real-time software components. In this paper we target real-time components operating on a distributed resource infrastructure. Furthermore, we target a class of software components which demonstrate
dynamic resource consumption behavior. A prime example of such components is a multimedia software component. In the paper, we present a framework supporting multi-resource end-to-end resource reservations. We reserve resource bandwidths on both processor resources as well as on the network resources. The proposed framework utilizes a Multiple Input Multiple Output (MIMO) controller which adjusts the sizes of reservations tracking the dynamic resource demands of the software components.
Finally, we present a case study using a multimedia component to demonstrate the performance and efficiency of our framework.
