To cope with heavy loads due to new technologies such as cloud computing and data-centers' the networking of devices on internet became more complex.To deal with complex demands the networks have to be smarter and able to control and manage the devices better hence the interest in software-defined networks.To effectively address the practical challenges of these networks the researchers have developed an open standard called OpenFlow.With OpenFlow firmware installed on routers and switches, users can use software to tap into flow tables and control a network's layout and traffic flow as fast as possible and flexibly.This software-based access allows inexpensively and easily to test new switching and routing protocols being developed from time to time.In this paper we present a dynamic load balancer that can enable application specific routing algorithms rather than network based static routing.The load balancer has been simulated on OpenFlow standard and it has been proved that load balancer is much faster and effective.
