LOAD BALANCER AND THEREOF METHOD USING GENETIC ALGORITHM

摘要

The present invention discloses an apparatus and a method for distributing a load on an SDN using a genetic algorithm. The SDN phase load distributing apparatus using the genetic algorithm according to the present invention calculates the amount of load given to each controller of the SDN and the standard deviation of the amount of the load and calculates the load calculated by the load unbalance determining unit part; A load imbalance determination unit for determining whether an amount of load given to each controller is unbalanced or unbalanced based on the amount and standard deviation of the load, and for providing the determination result to the load adjuster; And a load adjustment unit for adjusting the amount of load applied to each controller when the load imbalance determination unit determines that the amount of load applied to each controller is unbalanced. According to the present invention, the amount of load given to each controller in the SDN environment using a plurality of controllers can be expressed by a numerical value. In addition, the standard deviation between loads can be used to detect an imbalance in load imposed between the controllers, that is, a load imbalance, and the load distribution algorithm can adjust the amount of load on the controller given an excessive load. Finally, reliability of the network can be guaranteed by preventing connection failure between the controller and the switch due to the load imbalance.
