specification, management, conflict resolution, and enforcement To increase the assurance with which agents can be deployed in of policies within the specific contexts established by complex operational settings, we have been developing the KAoS policy organizational structures. Following a description of these and domain services. In conjunction with Nomads strong mobility capabilities (section 2), we will conclude with a brief summary of and safe execution features, KAoS services and tools allow for the current applications (section 3) and a brief outline of future specification, management, conflict resolution, and enforcement directions (section 4). of DAML-based policies within the specific contexts established by complex organizational structures. In this paper, we will KAoS AND NOMADS POLICY AND discuss results, issues, and lessons learned in the development of DOMAIN SERVICES these representations, tools, and services and their use in militaryKAoS is a collection of componentized agent services compatible and space applications with several popular agent frameworks, including Nomads [27], the DARPA CoABS Grid [18], the DARPA ALP/Ultra*Log

Abstract. NOMADS is a Java-based agent system that supports strong mobility (i.e., the ability to capture and transfer the full execution state of migrating agents) and safe agent execution (i.e., the ability to control resources consumed by agents, facilitating guarantees of quality of service while protecting against denial of service attacks). The NOMADS environment is composed of two parts: an agent execution environment called Oasis and a new Java-compatible Virtual Machine (VM) called Aroma. The combination of Oasis and the Aroma VM provides key enhancements over today's Java agent environments.
