A Review of Deterministic and Non-deterministic Load Balancing Mechanisms in Software Defined Networks

Managing conventional networks has become challenging due to rapid network growth and emergence of new technologies like big-data and cloud computing. To overcome such issues the new paradigm concept is suggested known as Software Defined Network (SDN). To comply with quality of services (QoS) of networks and maximize the reliability of network the load balancing issue must be considered. In a traditional network, load balance is predicated on the network’s current data flow. On the other hand, SDN controllers can establish better load balance in wider perspective of network. This paper surveys the load balance strategies in SDN network based on deterministic and non-deterministic approaches. Furthermore, the major problems of some algorithms have been addressed so that investigators might use improved load balancing approaches in future.
