Desarrollo de una aplicación para la implementación de calidad de servicio por priorización de tráfico sobre una Red Definida por Software (SDN)

Abstract

This Project is composed by four chapters. The first chapter presents the characteristics of Software Defined Networks their components and structure as a base of the project. The second chapter presents the design and implementation of the application that provides quality of service, it is developed in Java programming language and performs the analysis of the TCP and IP headers as well as the source and destination physical ports of the packets sent to controller. According to the type of packet found, the respective rules are sent to the switches in order to know how to process these packets and prioritize traffic; additionally, it creates the SDN where the application will work, it consists of two switches, the controller Floodlight and five hosts. The third chapter presents the tests of conectivity through the network and functionality of the application that provides quality of service, making traffic captures and measurements of jitter and latency. A referencial budget with the cost of the project’s implementation, is included. The four chapter presents the conclusions and recomendations. The annexes with the tutorials and aditional information are attached at the end of the document.
