Resumen en inglés

Currently, with the constant demand growth of devices connected to the internet many times we see collapses in the network, hence surged the Software-Defined Networks (SDN), a new paradigm of nets and also a concept called load balance is added that in few words improves the response time of the servers which we are connected using different mechanisms according to need. This research addresses the topic of Load Balancing in Software-Defined Networks using Quality of Service algorithms to ensure and optimize the proper functioning of the network in terms of velocity and data traffic. The main objective is to perform and apply these algorithms in the SDN controller where the best route of all the links in the network is located to circulate the desired traffic between the desired hosts; it should be noted that the network is simulated in a virtual environment, with a tool called Mininet, within which all the network parameters are configured and can be attached to the SDN controller. In short, the algorithms were successfully applied and is appreciated the big difference between the before and after of the experiments, the improvements in the network is due to the delay time and the bandwidth according to the standards meets with Quality of Service; with the tabulation of all these data was created graphs where we see the trend of the values in the network states. As a conclusion we have that the quality of service algorithms are a good option for the realization of load balancers in this type of networks, whatever the type of data that manages the network, the improvements will always be noticed in the functioning of the network and the response times of the request made to the different servers.
