Arquitetura de gerenciamento de redes baseado em agentes móveis mutáveis

Abstract

Normally, the network management systems operate using client-server architectures and SNMP protocol (Simple Network Management Protocol). The interaction between the management station and its managed points involves a great volume of traffic information, that can generate overload in the network. Studies indicate that the use of mobile agents as mechanism of decentralized management can reduce the exchange of information and consequently minimize significantly the system overload. However, the use of highly specialized agents can increase the system complexity and also generate overload, once for each management necessity a new specialist agent will have to be created and sent to the intervention point. In this thesis a network management architecture based on changeable mobile agents is proposed. The proposed architecture combines the main existing network management architectures associated with the use of changeable mobile agents, developed using the JADE (Java Agent Development Framework) architecture and the JavaTM platform. This new architecture aggregates characteristics of these architectures, proposing less complex and more efficient methods than can be applied in the network management, reducing the human intervention necessity with self-management characteristics.
