Dynamic Reconfiguration in Reservation-Based Scheduling: An Optimization Approach

Abstract: Reservation-based scheduling mechanisms have successfully been used for supporting real-time applications whose tasks exhibit high variability in their execution or release times. Indeed, such mechanisms are able to preallocate system bandwidth to the application tasks so that temporal isolation between them is ensured. However, bandwidth allocation is usually based on off-line policies, which may not be suitable for real-time applications that are structured as having several modes of operation, each one requ… Show more

“…Each mode is a set of active resources, a local schedule on each resource, and a network configuration [16]. A multi-mode approach has also been used to achieve efficient use of resources; for instance, dynamic resource allocation techniques, such as adaptive servers [1], [2], [8], [9], have been developed for this purpose. Similarly, energy-efficient task allocation techniques that consider mode execution patterns have been proposed (e.g., [12], [13], [23]).…”

“…Server SA serves a single task τA with worst-case execution time (WCET) of 2ms and period of 20ms which we will denote as (2,20). In Old Mode, server SA has a reserved slot of 1ms in a TDMA cycle of 10ms denoted as (1,10). In New Mode, server SA has parameters (3,12).…”

“…de Olivera et al [10] addressed the problem of finding optimal CBS parameters and dynamically reconfiguring the servers, offering support for multi-mode adaptive real-time applications. Valls et al [29] presented an adaptation protocol based on the definition of a contract model for filtering peaks in resource demands where applications are modeled with periodic, continuous, and imprecise tasks.…”
