Aprimorando o desempenho de redes em ambientes de nuvem através do roteamento por múltiplos caminhos

Abstract

Although cloud computing seems to be something new, its idea is relatively old, it emerged in the 60’s from the ideas of pioneers like J.C.R. Licklider and John McCarthy. Since then, its practicality, flexibility and efficiency have attracted more and more attention from industry and academia. However, a problem that must be taken into account is the drop in performance due to the virtualization layer, with the need for a large amount of bandwidth, and the cost of hiring such a resource. One of the methods found would be the aggregation of links used to increase bandwidth. This work proposes an improvement to the aggregation of links, taking advantage of MPTCP for the allocation of resources in the cloud. However, the implementation of a scenario for such improvement is unfeasible, without first having a notion of how the network will behave for the improvement. For this, a model, capable of providing a behavior close to reality, is essential. For this reason, we use Petri nets, a graphical and mathematical tool, thus being able to evaluate the performance of the net with the MPTCP technology.
