Diseño de Prototipo de Aplicación para Control de Admisión de Flujos en una Red SDN

Software-defined networks (SDN) come to solve problems that conventional networks face such as: service quality problems (QoS), security, mobility management and scalability. There is no mechanism to avoid network congestion where packets are discarded generating a bad QoS for the user. The project is a FAC (Flow admission control). which determines when to admit or deny incoming flows to the network according to the availability of resources on it. This admissionmodule is in the control plane. As packet traffic on the network fluctuates over time, the controller (Ryu) of the SDN, based on its knowledge of the network created, must be able to decide how to achieve the prerequisites. For this purpouse, the admission control architecture design is created. Where, we have the traffic identification, consult to a database and admission definition according to the conditions generated in the predefined QoS profile. Because the environment is completely virtualized, Mininet is used. It is a network simulator, which is capable of creating virtual hosts, controls, switches and links, where each component and each node can be analyzed separately. Thus guaranteeing a correct study of the network and obtaining realistic results.
