Integrando agentes móveis com sistemas legados para gerenciamento de redes ATM heterogêneas.

Abstract

This thesis presents the integration of mobile agent technology with network management legacy systems as a proposal for the solution of the following problems: the overload of information in the bandwidth because of the continuous increase of the servers connected to the network; centralization aspects of the main network management legacy systems and finally, the challenge of ATM heterogeneous network management. Concordia System, created by Mitsubishi Electric Information Technology Center America, was employed as a development platform for mobile agents. SNMP from IETF was used as a management legacy system for data network. Concordia was chosen because, written completely in Java, provides portability and allows the execution of its agents anywhere and at anytime with security, mobility, management and monitoring – all the necessary characteristics to achieve the perfect environment for the mobile agents. SNMP that has the simplicity of the project as its main advantage was chosen because of its wide use and support by great part of equipment manufactures. Java class libraries from AdventNet API package were used to allow mobile agents to execute GET and SET SNMP commands and therefore access management information. This thesis is part of the AMI Project “A CORBA Distributed Platform with Intelligent Mobile Agents to Manage Networks and Services” of Laboratory of Computer Network and Software Engeneering – LARCES of State University of Ceara – UECE. First, AMI Project proposes the implementation of an environment throughout platforms that already exist such as Concordia, and second the development of its own platform for mobile agents developed at LARCES/UECE. Initially, based on AMI Project, Concordia mobile agents were developed to manage PVCs among devices that belong to “High Speed Metropolitan Network of Fortaleza (REMAV-For)” and, afterward, to other REMAVs throughout Brazil.
