Abstract

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. We have developed QoS management features, QoS Enabled Dissemination (QED), that extend 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. Experiments evaluate QED and Phoenix's ability to (1) provide IM in the Wide Area Network (WAN) context of the satellite communications, which includes long latencies and background traffic not under QED control; (2) control and utilize active-precedence and queue management features provided by the WAN; (3) handle severe network overload, network disruptions, and dynamic changes in policies; and (4) successfully enforce deadlines and information replacement policies.
