Paper Abstract

Effective network-centric warfare requires information exchange with suitable quality of service (QoS) to meet the warfighter's needs. Information delivered too late or with the wrong resolution, form, or precision is insufficient for the user to perform his role in a warfighting scenario. Key characteristics of network-centric warfare environments, as instantiated by the Global Information Grid, are dynamic reconfiguration and interoperability, in which Communities of Interest (COIs) can be formed and reformed dynamically to respond to real-time threats and unfolding situations. There is a need for a QoS management capability that can support the dynamic interoperability and real-time requirements of networkcentric warfare. In order to be effective, this QoS management capability must manage the production, delivery, and consumption of information within available resources, mediate competing demands for resources, and adjust to dynamic conditions. In this paper, we describe the architecture for a QoS Management System (QMS) that works alongside information management systems in dynamic COIs. The QMS provides QoS management (including resource management and quality of information management) in dynamically changing, mission driven environments for interoperating assets within a COI and for assets and resources shared among COIs. The QMS provides mechanisms for QoS policy specification, QoS enforcement and monitoring, dynamic resource allocation, and application adaptation in dynamic COIs. It is based on a layered architecture that maps mission requirements to QoS policies and enforcement. We describe the QMS architecture, prototype implementation, demonstration, and evaluation. Based on these experiences, we also discuss future research directions.
