Abstract

Maintaining Quality of Service (QoS) in distributed operating systems is a critical challenge, especially in dynamic and resource-constrained environments. Traditional QoS mechanisms often fail to adapt effectively to unforeseen failures or load spikes, leading to abrupt service disruptions. This study reviews the concept of hybrid graceful QoS degradation, a paradigm that combines multiple strategies to ensure continuous, albeit potentially reduced, service availability. By intelligently integrating techniques like resource reservation, priority-based scheduling, adaptive algorithms, and layered QoS, distributed systems can dynamically adjust their performance in response to changing conditions. This review analyses the various techniques used in hybrid approaches, evaluates their strengths and weaknesses, and discusses the challenges associated with their implementation. We explore the importance of effective monitoring, decision-making, and communication protocols for successful degradation. Furthermore, this study identifies emerging research directions, including AI-driven QoS management and edge computing integration, highlighting the on-going evolution of QoS strategies in distributed environments. This review underscores the significance of hybrid graceful degradation in building resilient and user-friendly distributed systems.
