5. CoAX /Tech Briefing - 4 GITI/ISX The CoABS Grid u The CoABS/Infrastructure code provides a framework for integrating diverse agent-based systems, and provides additional common services. u The Grid allows agents to find services and other agents so that agent teams can be dynamically formed to solve context-based tasks. u The Grid is built using Jini TM technology. Direct agent communication is provided using message queues built on JAVA RMI. Grid Logging Markup Language based on XML.

7. CoAX /Tech Briefing - 6 Boeing/UWF - Agent Domains DM An agent domain consists of one or more agents registered with a common Domain Manager which provides for common administration and enforcement of domain-wide, platform- specific, and agent-specific policies.

8. CoAX /Tech Briefing - 7 Agent Domain Management in CoAX u Broadens typical distributed security concerns to include: u Communication and access management: Who can communicate with whom for what services? u Registration management: Who can join the domain under what circumstances? u Resource management: Who can have which kind and how much of a given computing resource? u Mobility management: Who can move where under what circumstances? u Conversation management: What constraints govern interaction between conversing agents? u Obligation management: Who is not meeting commitments? Initial capability shown in six-month demo Initial capability slated for nine-month demo Initial capability slated for 2001-2002 demos

11. CoAX /Tech Briefing - 10 AIAI I-X Process Panel u Initially maintains an overview of the current status the coalition C2 processes in accessible shared military terms. u Later adds the ability to monitor, plan and control the coalition C2 processes. u Can take on and address “issues” in the C2 process. u Links to and assists with domain management, authority, exception management and other Grid management services. u To be packaged as generic task and process management facilities that can be made available to other Grid applications.

13. CoAX /Tech Briefing - 12 DERA Master Battle Planner u Visual planning tool for air operations. u Map-based graphical user interface - operator builds scenario and air missions using simple dialogs and “point and click” techniques. u Analyzes plans (identifying over-tasking, GANTT charts, animated flyout facility) u Obtains data on targets and assets from other agents. u Integrates air missions (e.g. air transport) and weather forecasts from other agents into the air visualisation. u Informs AIAI’s Process Panel of current planning status.

16. CoAX /Tech Briefing - 15 AFRL/GITI/BBN CAMPS Mission Planner u u Develops schedules for aircraft to pick up and deliver cargo within specified time windows. u u Takes into account a large number of constraints (aircraft & port capabilities, crew availability, work schedule rules) u Can be tasked by other agents. u Domain-aware agent obtains scheduled air transport flights and forwards them to Master Battle Planner for integration into the air visualisation.

18. CoAX /Tech Briefing - 17 USC/ISI Ariadne Weather Agent

19. CoAX /Tech Briefing - 18 LM ATL EMAA/CAST AODB Access Agent u Provides access to AODB via XML formatted Grid messages. u Supports different kinds of queries: one shot, update, and persistent. u Will be evolving EMAA/CAST technology to create a deliverable generic Grid-aware core agent engine to other end users. This technology will be configurable and is intended to easily allow access to alternative sources.

20. CoAX /Tech Briefing - 19 LM ATL EMAA/CAST AODB Access Agent

21. CoAX /Tech Briefing - 20 Lm ATL EMAA/CAST AODB Access Agent

22. CoAX /Tech Briefing - 21 USC/ISI Open Information Access u Provide real-time access to Web data sources u Tools for learning wrappers to extract data for semi-structured sources u Agents learn the structure of data to support: u Source verification automatically detect when the source no longer provides correct data (possibly because the source has changed) u Source reinduction automatically revise wrapper when site change

23. CoAX /Tech Briefing - 22

24. CoAX /Tech Briefing - 23 Resource Control and Security in NOMADS u Dynamic and fine-grained resource control u NOMADS enforces security policies specified by the KAoS domain manager u Security policies include limits on CPU, disk, and network resource usage u Resource consumption monitoring u NOMADS Guard constantly monitors the resource consumption of the GAO agent u When the guard detects a potential denial of service, the guard reduces the resource limits available to the GAO agent

28. CoAX /Tech Briefing - 27 MIT Robustness Service u The Challenge u Open systems (like coalitions) include unreliable agents (bugs, malice) and infrastructures u The MIT Robustness Service u Monitors agent ‘health’ via polling u Tracks inter-agent commitments u Controls task cancellation, result caching & task re- announcement u Maintains reliability information (failure avoidance) u Informs registry of hung agents

30. CoAX /Tech Briefing - 29 Michigan Multilevel Coordinator Agent u Analyses the alternative plan spaces of coalition functional teams that plan independently and act asynchronously u Works top-down with plans chosen by teams to predict unintended interactions (resource contentions; friendly fire). u Identifies candidate resolutions (timing or action constraints). u Notifies process panel of possible plan conflicts and computed workarounds. u Operationalizes/enforces coordination decisions selected. u Given more time, isolates and resolves conflicts more precisely and efficiently. u Allows planning and coordination decisions to be postponed until runtime conditions become better known. u Packaged as a Grid-aware component that can be proactively executing and utilized by the AIAI Process Panel.
