Mobile Agents - A Solution for Network Monitoring.
ABSTRACT Currently, most network management systems operate on SNMP. This protocol use the management station that provides a user interface to the network manager and interacts with agents that manage remote access to the Management Information base. In certain circumstances (e.g. at times of network stress), this interaction generates significant traffic that overloads the management station. A distributed paradigm is a revised way to perform management functions when networks grow significantly. In this sense, use of mobile agents is an option to distribute the network management. These agents move to the place where data are stored and select information which the user wants. They decentralize processing and control and as a consequence, reduce the traffic around the management station and distribute processing load. The main purpose of this work is to use mobile agents paradigm to implement the network monitoring(Instead of using the conventional client-server approach) to alleviate load created by network management protocols and to investigate the performance of network. This paper proposes a security model for communicating through Mobile agents. This paper proposes to implement the network performance monitoring using mobile agents. Some principle parameters that are to be monitored are: source ip, destination ip, no of packets, startup time, down time and bandwidth utilization of the network component. These parameters provide useful information to model the traffic through the network for further enhancements. The model is very robust when compared with SNMP. The model performance is tested for security using ForEx agents.

Conference Proceeding: A network management framework using mobile agents[show abstract] [hide abstract]
ABSTRACT: In this paper, we present a framework that has the ability to perform network management tasks on heterogeneous networks. Our framework handles the inability of many network devices to run mobile agents. To cope with fast evolution, we present a modular approach that provides tools to build quickly network management agents to perform virtually any task. While the main focus of the project is the framework, we present an example of mobile agents that are able to locate a fixed set of network failure and detect the possible causes accurately.Electrical and Computer Engineering, 2003.

Conference Proceeding: Decentralized SNMP management with mobile agents[show abstract] [hide abstract]
ABSTRACT: The mobile agent paradigm can be employed effectively for the decentralized management of complex networks. Nevertheless, legacy management protocols such as SNMP need to be supported for reasons of migration and efficiency. We show how the integration of the two paradigms leads to a flexibly adjustable decentralized management architecture. NetDoctor is a network management application framework that allows the monitoring of hosts in a heterogeneous network. Mobile agents may query local or remote SNMP agents, process the status data, and perform certain corrective actions. The system supports run-time adjustment and reconfiguration. A quantitative analysis underlines the benefits in respect to the network load reductionIntegrated Network Management, 1999. Distributed Management for the Networked Millennium.

Conference Proceeding: Using mobile agents for network performance management[show abstract] [hide abstract]
ABSTRACT: Mobile agent frameworks have attracted a lot of attention in recent years, seen as counterparts of static distributed object frameworks but allowing also for object or agent mobility. A lot of research is currently being carried out trying to assess their applicability to network management and control environments. In this paper, we present our experiences of using a mobile agent framework to design and realize a performance management system which exhibits “constrained mobility”, constrained in the sense that performance monitoring agents are sent to execute within network elements and stay there until their task is accomplished. We present the architecture, design and implementation of such a system, compare and contrast it to static object approaches and present a detailed performance comparison to a similar Java-RMI based implementation, trying to assess the overhead of mobile agent solutionsNetwork Operations and Management Symposium, 2000.
