Diseño de una red de proveedores de servicio con SDN y segment routing para mejorar el rendimiento de la red.

Abstract

The objective of this work was to design a network of service providers defined by software (SDN) and segment routing (Segment Routing) to improve network performance, different routing protocols, ways to integrate both technologies and architects. To determine the performance, stress tests were carried out with different amounts of traffic using the TRex traffic generator software, the Wireshark capturer and the Omnipeek analyzer, the behavior was observed based on network parameters to conclude which routing is better. To integrate SDN into the network with Segment Routing, the Opendaylight controller has been implemented, which is free software that can communicate with network devices to obtain all the information about it and configure it with the network configuration protocol (NETCONF). Once the values for the network parameters were obtained, a statistical analysis was done with the Wilconxon test to determine if there was a significant difference between the routing technologies. With the SDN controller, the network was communicated to be able to manage and configure it in a better way thanks to the different native tools offered by the software. It is concluded that Segment Routing has better performance than routing by the shortest path first (OSPF) protocol for the deployment of service providers and that Opendaylight is a software through which the network can be managed and configured in real time. easier due to its graphical interface. It is recommended to study the Northbound interfaces of the Opendaylight controller that, thanks to their communication with application programming interfaces (APIs), application programming tools such as POSTMAN can be used to publish configuration files and thereby automate the network.
