Executive Summary

Information Management (IM) services support the discovery, brokering, and dissemination of mission-critical information based on the information's content and characteristics. IM services support the dissemination of future information (through subscriptions) and past information (through queries) regardless of its source. To be useful across enterprise and tactical environments, IM services need mission-driven Quality of Service (QoS) features as part of their core functionality. The authors have developed QoS management features, QoS Enabled Dissemination (QED), that extends an Air Force Research Laboratory (AFRL) developed set of IM services, Phoenix. This paper describes the results of a joint services experiment evaluating QED and Phoenix in a US Navy scenario involving multiple ships connected by a Disconnected, Intermittent, Limited (DIL) satellite network.
