Routing as well as the management of communication networks that support hybrid types of communications requiring quality of service is a hard problem. We present here a framework1 that decomposes the network into a hierarchy of abstract views of the network that summarizes the available bandwidth resources and highlights bottlenecks in the network in order to reduce the complexity of the previously...
This paper deals with using an evolutionary algorithm (EA) as a prototyping tool to develop and refine a multi agents system (MAS) for problem solving. In the case of (distributed) solving, MAS may lack some knowledge about the solving mechanism. Using a GA as a prototyping tool thus enables to extract heuristics for use in the MAS design. This approach, based upon a model conciliating both EA and...
Very large networks with thousands of applications and millions of users pose serious problems to the current traditional technology. If synchronised client behaviour exists, then the limitations are even stronger. Cooperative agent systems can be a suitable technology to answer to these requirements if some aspects of the architecture are carefully designed. Particular attention should be given to...
This paper illustrates a new approach to the problem of making a logical network resource configuration, adapt to customer utilisation. This is to be achieved through the use of distributed multi-agent based control techniques. The agents have goals derived from different quality metrics, which the network has to provide. In ATM networks a well designed Virtual Path Connection (VPC) overlay network...
A simple mechanism is presented, based on ant-like agents, for routing and load balancing in telecommunications networks, following the initial works of Appleby and Stewart [1] and Schoonderwoerd et al. [32,33]. In the present work, agents are very similar to those proposed by Schoonderwoerd et al. [32,33], but are supplemented with the ability to perform more computations at switching nodes, which...
This paper covers the design and implementation of a generic model, based upon Mobile Agents, to perform PVC configuration management functions in multi-vendor ATM networks. The paper introduces an alternative or complement to existing ATM configuration management solutions. In it, an autonomous mobile agent travels from switch to switch to perform its configuration duties. A prototype implementation...
In this paper, we present several approaches to making the process of configuring network devices easier than is currently the case. Configuring a device requires that a number of attributes in the network and on the device be set as well as certain software components be installed. For example, a printer requires that its drivers are present on workstations that will be using it. Currently, the manager...
We present an approach to resource allocation in telecommunications networks based on the interaction of self-interested agents which have limited information about their environment. A system architecture is described which allows agents representing various network resources, potentially owned by different real-world enterprises, to coordinate their resource allocation decisions without assuming...
Agent technology promises to increase the flexibility and power of telecommunications management systems and services. This paper describes ongoing work that, through prototyping and experimentation, is aiming to understand the practical implications and benefits of applying agent technology to the management of problems related to service application software. Agents are seen to play a central role...
This paper describes how multiple interacting swarms of adaptive mobile agents can be used to locate faults in networks. The paper proposes the use of distributed problem solving using mobile agents for fault finding in order to address the issues of client/server approaches to network management and control, such as scalability and the difficulties associated with maintaining an accurate view of...
This paper describes the design and implementation of INCA, an open architecture for the distributed management of multi-service networks and systems applications. The Intelligent Network Control Architecture is populated by stationary and mobile intelligent agents. These agents perform monitoring and control of network and systems components, thereby supporting the integrated management of networks...
Using as little mathematical detail as possible, we present the use of transformations between process related languages and dynamic entity-relationship models. The work incorporates our earlier research in schema integration and the integration of multi-agent architecture designs to handle problematic cases of global inconsistency in distributed information systems. The verification methods in first...
This paper describes the design and implementation of a unique cooperative agents testbed and tool for launching cooperative agents in an environment that addresses diverse applications for the difficult problem of seamless personal information networking (SPIN). The real-world SPIN testbed is aimed at two difficult applications, namely seamless messaging and intelligent network management. Both applications...
Personal mobility — a fundamental characteristic of Nomadic Computing — creates an environment in which a user roams without a wireless laptop or a mobile phone and yet enjoys anytime, anywhere network accessibility. This paper gives an overview of Nomad's Personal Access System (NPAS), OSI application layer software that provides a personal mobility environment within a virtual network. In addition,...
This paper describes the architecture and operation of a Multi Agent system for providing end users with an intelligent interface for video conference and cooperative work services. The system consists of negotiating Agents: the Personal Communication Agents offers the user an intelligent interface to the service, it negotiates the best conditions in terms of quality of service and costs, the Service...
As agent technologies are increasingly being involved in telecommunication-related applications, the need for open standards is becoming critical. During the past years, different scientific communities gave birth to different standardization actions, such as the Foundation for Physical Intelligent Agents (FIPA) and the Object Management Group's MASIF (Mobile Agent System Interoperability Facilities)...
This paper describes the JIAC project, an open and scalable agent architecture. The telecommunication market of today being in continuous expansion is in need of a platform to access the resulting growing demands. JIAC-Java Intelligent Agent Componentware-provides an agent based platform to meet those demands of the telecommunication applications. The requirements of those applications are outlined...
