QoS algorithms for load balancing in Software Defined Networks

Abstract

Internet has created a digital society where most are connected and has Access from anywhere, however it causes networks collapse, creating the need of use new paradigms  in  comunications,  software-defined  networks along  with  load  balancing present a solution to this problem applying quality of service algorithms they use mechanisms to improve the response time of servers which clients connect.It was proposed to make a load balancer applying quality of service algorithms in the networks defined by software, analyzing step by step the structure that assembles a load balancer applied in the networks defined by software, interpreting the quality of service politics regarding data traffic over a network refers to achieve set up the tools that were used to implement the simulation of the network and finally points out the productivity of the networks defined by software applying load balancing by means of servicequality algorithms. The network was simulated in a virtual enviroment using the mininet tool to configure the network parameters and attach it with the openDayLight network controller managing to find the best route in all possible ways for traffic circulate among hosts. Was possible to observe a big difference between  before and after of measurements in the network, these improvements were based on the delay time and the bandwidth following the guidelines of quality serve, data was tabulated and was created graphs to observe trends in the network states, coming to the conclusion that the quality of service algorithms applied to software-defined networks to balance loads improve significantly the functioning of the network.
