Roteamento multicaminhos em redes definidas por software usando p4

Abstract

The increase in popularity of computer networks like the Internet, has lead to a significant increase in the number of services that use them, making it necessary to rethink their performance and availability. In order to mitigate those problems, the first step is to gather network metrics and after it configure the network to achieve some goal. An alternative that is gaining a lot of space in the industry are the Software Defined Networks. These are networks where the data plane is physically separated from the control plane, in a way that it is possible to configure the whole network from a single software, and also gather network metrics in an easy and dynamic way. This work presents an alternative to the most used Sofware Defined Networks protocol, called OpenFlow, in the scope of multipath routing. The chosen alternative for this work was an architecture that uses the P4 language.
