The excessive growth of internet traffic and broadband services has initiated the requirement for a bandwidth flexible network making services more capable of elasticity. The issue of network management can be brought to simplification with the emergence of Software Defined Networks (SDN) through the introduction of a programmable network. The major problems such as scalability and availability has been addressed which may lead to a cause of failure in load balancing. In order to ensure dynamic load balancing within a SDN, the technique of IP load balancing and provision of a congestion free network has been employed through comparison between random and round robin approach. The severity of path loss has also been addressed to convey a simple, essential and add-on network paradigm within the SDN architecture. Moreover, 100 and 500 packets have been transmitted in the described load balancing scenarios where packet throughput is the main concern, and 15% of the link losses have been observed in path loss. The results represent profound traffic steering capabilities bringing up an efficient network performance.
