Análise da resiliência sobre topologias de redes definidas por software em ataques iminentes

Abstract

This work presents the research of the resilience of topologies in software defined networks in imminent attacks. It was evaluate three topologies, ring, tree and torus, because they were corelate for classical network environments. For geting the data were built emulated scenarios using the tool Mininet, each scenario were performed 31 times for the date capture, the atacks were generate using T50 denial of service tool, the data collection were made using Tcpdump, a packet analyzer and Shell Scripts to calculate the time between each event defined as the start of the experiment, the time death of the topology and the time of return to operation of the topology. The data capturaded were analyze using descriptive statistics and survival analysis using R to perform the analyzes. Finally, it was observed that the torus topology offers greater resilience, followed by topology ring and tree, between scenarios the main difference that can be reached is the redundant routes that topology torus and ring presents, this way the topology ring presents two routes in each switch and the torus topology presents four routes in each switch of comunication.
