IP-Based Hashing Load Balancer in Software Defined Networking

Abstract

Software-Defined Networking (SDN) is a new principle in the networking paradigm where control and management are centralized and decoupled from data plane, thus making the network programmable and uses open interfaces between the devices in the control plane (controllers) and those in the data plane. Load balancer is a system that distributes network or application traffic across a cluster of servers depending upon load balancing strategy. Here, IP hash-based load balancer algorithm has been deployed over SDN Framework and its performance over other load balancing algorithms; round robin, weighted round robin were evaluated and compared using HTTP server client model with exchange of different file sizes samples and standard dataset files. Further, the implemented model was evaluated using opensource network evaluation tool iPerf. The result showed that the performance of IP based Hash algorithm was observed to be slightly better among other in Software defined network.
