“…This is similar to the approach used in PDL [10], where internal events are used to link the execution of policies. However, in PDL only local events were considered, whereas here events can be sent to remote nodes performing a given role.…”

Abstract. This paper defines an operational framework for specifying and establishing secure collaborations between autonomous entities that need to interact and depend on each other in order to accomplish their goals, in the context of mobile ad-hoc networks. We call such collaborations mission-oriented dynamic communities. We propose an abstract model for policy-based collaboration that relies on a set of task-oriented roles. Nodes are discovered dynamically and assigned to one or more roles, and then enforce the policies associated with these roles according to the description of the community. In this paper we focus on the roles that are needed to provide management and security functions for dynamic communities.

Mobile Ad hoc NETworks (MANETs) have been adopted as the building blocks of future military tactical networks. We believe that the dynamic nature of such networks makes the automation of both network management and network planning a necessity rather than just a desirable feature. The creation of DRAMA, a policy-based network management system designed for managing dynamic MANETs, is the first step of this automation effort. Since the current practice requires that policies be specified manually, which we have found to be a challenging task, it is highly desirable to automate the generation of network management policies by network planning. In this paper, we present our vision of automating the management and planning of future tactical networks, describe what has been accomplished and ongoing activities, and discuss future work towards achieving this vision.

“…Ponder is a declarative, object-oriented language that supports events, constraints, roles, templates and other useful language features. [16,17]), like Ponder, is an eventcondition-action (ECA) declarative language though it does not have all the features that Ponder has. PDL is reviewed by Sloman in [1].…”

Abstract. Autonomic behaviours in network operations will alleviate much of the labour intensive and error prone interventions of today's complex networks. The Service Provider must be able to manage the infrastructure and services at an abstract level, focusing on what the desired behaviour should be rather than how it might be specifically achieved. Policy-Based Network Management (Pbnm) appears as one of the leading mechanisms to describe desired behaviours and abstract the programmability of an autonomic network infrastructure to the Service Provider. For massive-scale and complex networks, the current understanding of the Higher Level to Lower Level (HL→LL) refinement process commonly used in Pbnm today is not completely effective. One problem encountered is the need to provide a bind mechanism between Higher Level and Lower Level policy specifications such that cross-layer policy requests in the policy continuum can be made by lower policy layers in a dynamic policy refinement cycle (LL→HL→LL). In this paper, we illustrate the problem with a policy-based simple admission control (SAC) application. We then show that policy specifications with a join operator ( ) simplify the SAC specification. We also investigate the performance considerations of this enhancement in Internet size applications. Our future goal is to provide a policy inference engine that can support complex specifications appropriate for Pbnm systems that support autonomic behaviours in large networks, made of Network elements with realistic memory and processing constraints.
