Policy and Quality of Service Management for Enterprise Web Services Using policy-based information management to meet diverse mission objectives for the Department of Defense

摘要

The vision of a Joint Battlespace Infosphere has evolved within the US Department of Defense as an internet-like foundation to provide tailored information services and flow among producers and consumers of information needed to support diverse mission objectives. The architecture envisioned is based on a loosely coupled information environment using Commercial standard web service protocols and policy-based information dissemination management techniques to influence the flow of information between publishers and subscribers. The types of policy considered range from the "do no harm" policies of security management to the "do some good" policies of maintaining end-to-end quality of service. This paper describes research to address policy and quality of service management for web services. Topics discussed include: JBJ policy requirements, a policy architecture framework, an application domain example, and the identification of outstanding issues requiring further research in order to meet overall JBI objectives.
