Desenvolvimento de uma plataforma para gerenciamento e configuração de redes auto-organizadas

Abstract

Managing today's computer networks is a complex activity that requires great human effort to achieve the levels of availability and performance defined by applications. This scenario is aggravated by the introduction of new control components used in approaches such as SDN and NFV, which despite resolving important aspects for the flexibility and security of the network, introduce new points of failure. This complexity from the perspective of ISP represents more spending on OPEX, and from the perspective of users it represents more risk of breaking the SLA, which in certain cases can cause life risks and financial losses. Management automation through autonomous computing concepts has already been successfully applied to telecommunications networks through the SON specification by 3GPP, and represents a practical alternative for computer networks. We believe that it is possible to achieve high levels of automation of network management through the use of components responsible for the collection, analysis, learning, decision making and intervention in the network. In this context, the present work aims at specifying a self-organized network management platform for the automation of configuration operations in software-defined networks. This specification is presented in this thesis with different levels of vision starting from the definition of conceptual models responsible for the abstraction of self-organized networks and communication services; then by specifying an architecture for self-organizing networks, i.e. SONAr; by implementing a self-management framework; and finally, by the materialization of a self-configuration platform. This work applies the framework implementation to tests in emulated scenarios involving network initialization operations, device plug-and-play and service provisioning. The results obtained are promising in demonstrating both qualitative and quantitative compared to traditional approaches.
