Interest-based negotiation for asset sharing policies

Resource sharing is an important but complex problem to be solved. The problem is exacerbated in a coalition context due to policy constraints placed on the resources. Thus, to effectively share resources, members of a coalition need to negotiate on policies and at times refine them to meet the needs of the operating environment. Towards achieving this goal, in this work we propose a novel policy negotiation mechanism based on the interest-based negotiation paradigm. Interest-based negotiation promotes collaboration when compared with more traditional negotiation approaches such as position-based negotiations

Policy technologies for security management in coalition networks

The goal of policy-based security management is to enable military personnel to specify security requirements in terms of simple, intuitive goals. These goals are translated into the concrete system settings in a way that the system behaves in a consistent and desirable way. This technology minimizes the technical expertise required by military personnel and automates security management while allowing a high level control by the human in the loop. This chapter describes a framework for managing security policies, and an overview of two prototypes that simplify different aspects of policy management in the context of coalition operations

A Customer Service Management Architecture for the Internet

Managing services on the Internet is becoming more and more complex and time consuming for service providers since services are increasing both in number and complexity. Also the number of users per service is going up. A solution to this problem is to allow the service users themselves to partly manage the services they are using. This is called Customer Service Management, and it will both increase the perceived value of the services to the users as well as lower the operational costs of service management for the service provider. This paper presents an architecture for Customer Service Management in the Internet

Using message reflection in a management architecture for CORBA

The availability of object middleware, such as CORBA, is rapidly being accepted as a means for cost effective and fast development for a wide range of distributed applications. Distributed applications that are built using these technologies often comprise many objects and become more and more complex. The deployment of such large distributed applications requires a significant improvement of management methods and tools. In this paper, we present a management architecture for object middleware based systems. We use message reflection to extend the middleware layer with management capabilities, i.e. we monitor the application by observing the messages exchanged between the objects of the distributed application. We argue why management should be transparent to the application developer and show that message reflection supports this management transparency. We have compared different mechanisms to implement message reflection in CORBA, and argue why portable interceptors are the most suitable. Finally, we describe our prototype and the lessons we learned
