QED-
Quality of Service (QoS) Enabled Dissemination

 

Project Description
The QED project is researching, designing, and prototyping QoS capabilities for Information Management (IM) services, based on the publish-subscribe-query paradigm. QED is developing the following advanced capabilities:
* Timely delivery of information needed by tactical assets and warfighters in mobile scenarios with time-critical emergent targets;
* Tailoring and prioritizing information based on mission needs and importance;
* Responding rapidly to priority shifts and unfolding situations;
* Scaling to large numbers of users, operations, and resources; and
* Being robust to failures and intermittent communications.

 

Technical Approach
A multi-layered architecture with the following layers:
* A QoS Administration layer where the knowledge of mission requirements, policies, and higher level application knowledge is captured, managed, and utilized.
* An Aggregate QoS Management layer that translates higher level (i.e., mission-oriented) QoS policies into actionable policies, distributing them to local enforcement points, and mediating between conflicting QoS policies across many users of the information services and many control points.
* A Local QoS Management layer that enforces QoS policies at specific control points, utilizing QoS mechanisms.
* A QoS Mechanisms layer that includes specific QoS mechanisms that control and monitor resources and shape application behavior to the available resources.

Rigorous experimentation in a laboratory setting and in operationally-relevant operational experiments with the USAF and the US Navy.
