This paper introduces the concepts of a servicemanagement system for mobile agent-based services. Incontrast to several other approaches in whichagent-based applications are used to handle“traditional” network or service managementaspects, this paper describes a way to manage thedistributed agent environment itself. The proposedapproach was designed and developed by using OSI SystemsManagement concepts as a starting point, which are modified andadjusted in order to fulfill the new requirementsassociated with the mobile agent paradigm. However, thispaper does not cover integration or co-existence of the introduced agent management system (AMS)and traditional OSI management systems. Instead, theentire AMS environment is based on mobile agenttechnology. At present, this approach is validated inthe context of the European research project MobileAgent Environments in Intelligent Networks(MARINE).

The Mobile Agent (MA) technology is gainingimportance in the distributed management of networks andservices for heterogeneous environments. MA-basedmanagement systems could represent an interestingalternative to traditional tools built upon theclient/server model, either SNMP- or CMIP-based. Twomain requirements currently limit the acceptance of MAsolutions for management: the need of interoperabilityand the request for security. Without security,management systems cannot suit global untrustedenvironments, such as the Internet; withoutinteroperability, they cannot interact with existingtools and legacy systems. The paper describes an MA-basedmanagement system with security and interoperability asthe two main design objectives. It is an open managementframework that grants interoperability by providing compliance with CORBA, the most diffusedstandard in the area of object-oriented components. Inaddition, it is based on a thorough security model andprovides a wide range of tools and mechanisms to build and enforce flexible securitypolicies.

A network model is a fundamental part of anetwork management solution. Traditionally, networkmodels have provided views with static behavior andlimited state of the network elements that theyrepresent. This paper discusses an alternative approach tothe creation and maintenance of network models thatrelies on the use of mobile agents and the principle ofdelegation. In the intelligent network model proposed, behavior and state are part of the model andboth may be dynamically updated. A mobile codeenvironment being used to support the research isbriefly described.

This paper describes work carried out atUniversity College London to evaluate the use of MobileAgents (MA), written in Java, in network and systemmanagement. The work draws on experience fromconventional management systems based on ISO “CommonManagement Information Protocol” (CMIP) andInternet “Simple Network ManagementProtocol” (SNMP). These systems make use of theconcept of a “Managed Object” (MO). The paper describes the way in which the MOconcept has been translated into a form suitable forMA-based management and how the features of the Javalanguage may be used to express management information and to implement MOs. A platform has beenimplemented which allows MOs to be instantiated,controlled and stored. The platform also allows the easyproduction of MAs, their launching into the system and their subsequent management. Details of theplatform implementation are given and an initialassessment of performance is presented.
