Um método para coleta dinâmica e eficiente de estatísticas em redes programáveis

Abstract

Network monitoring is a fundamental activity for the correct and desired functioning of a computer network. In order to carry out this task, it is necessary that a method capable of retrieving network information and sending them to it’s administrators exists. Furthermore, it’s essential that this method is not only intuitive but also efficient, so no setbacks happen because of it. Knowing the need to monitor networks and the basic requirements for this goal, this work proposes a dynamic and efficient method for collecting statistics in programmable networks. To this end, three different subjects have been exhaustively studied: the P4 programming language, techniques for in-band telemetry and smart algorithms for statistics collection. The experimental results demonstrate that the proposed method is capable of dynamically adjusting itself to different traffic patterns in order to guarantee high monitoring efficiency. Besides that, the P4 language has shown itself to be an ideal tool for the presented scenario.
