A Hybrid Load Balancing Scheme for Software Defined Networking

Software-Defined Networking (SDN) has attracted great interest as a new paradigm in networking. In SDN, the control and data planes are decoupled, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the applications. An SDN controller is an application in a software-defined networking (SDN) architecture that manages flow control for improved network management and application performance. The overloading problem and SDN controller lacks a flexible mechanism to balance load among the distributed controllers. In this paper, it introduced a server load balancer technique using a hybrid algorithm as Least connection load-balancing algorithm and Weighted Round Robin load-balancing algorithm. The performance evaluation reveals that the proposed case study based on the hybrid algorithms with weighted WRR, and LC provided the better results of minimum time of Average ping for 100 packets of size 10240 Bytes is 80.766 ms, Max Bandwidth is 16.76 (Mb/sec), Max Transfer 30.05 (MB), and Max Interval is 9 Seconds, and Speed is 0.00555 Gb/sec.
