Summary In today's modern era, the internet usage has been developing tremendously. In data center network (DCN), the traffic has been rising constantly in the past few years. Hence, greater traffic of network needs several services such as Domain Name Service (DNS) to manage. It is not possible for one server to manage entire requests coming from client because of huge amount of traffic. To resolve this issue, load balancing is used. The major purpose of load balancing is to forward incoming client requests and distribute the traffic across various servers using customized algorithm which is deployed in the load balancer. Traditional load balancers are very costly and inflexible hardware. A substitute of this hardware is to use software‐defined network load balancers. The software‐defined networking (SDN) load balancers offer the facility to programmers to design and construct their own strategy of load balancing, which makes the software‐defined network load balancer flexible and programmable. This research proposes a novel algorithm that performs load balancing through calculating in advance the capacity of each and every switch across the path to which the packets are routed.
