On Developing Distributed Middleware Services for QoS- and Criticality-Based Resource Negotiation and Adaptation

The Global Resource Management System (GRMS) provides middleware services for QoS- and criticality-based resource negotiation and adaptation across heterogeneous computing nodes and communication networks. This paper presents GRMS's design, prototyping, and performance evaluation. We introduce GRMS design principles and two key concepts unified resource model and ripple scheduling--and describe our architectural design based on these concepts. Further, we present a decentralized end-to-end two-phase negotiation and adaptation protocol with the functionality of distributed, dynamic QoS adjustment and stream preemption. We discuss GRMS's system prototyping and lessons learned and report our experimentation and simulation results, providing insights into design and implementation of a middleware-based distributed resource management system.
