Contract-Based Quality-of-Service Assurance in Dynamic Distributed Systems
Lea Schönberger, Susanne Graf, Selma Saidi, Dirk Ziegenbein, Arne Hamann · 2022
To offer an infrastructure for autonomous systems offloading parts of their functionality, dynamic distributed systems must be able to satisfy non-functional quality-of-service (QoS) requirements. However, providing hard QoS guarantees without complex global verification that are satisfied even under uncertain conditions is very challenging. In this work, we propose a contract-based QoS assurance for centralized, hierarchical systems, which requires local verification only and has the potential to cope with dynamic changes and uncertainties.
