Performance comparison of Webservers load balancing using HAProxy in SDN

In software-defined networking, The network control plane's physical separation from the forwarding plane from where several devices are being controlled from the control plane. Therefore, software-defined networking is an emergent dynamic architect, quite manageable, cost-effective, and readily adaptable which makes it immensely ideal for high bandwidth hence, dynamic for today's application. Whereas, with this architecture the network controlling and forwarding functions can be separated, allowing the underlying infrastructure to be abstracted for applications and network services and making network control easily programmable. Hence, the fundamental element for building SDN solutions is the OpenFlow® protocol. In this paper, our crucial objective is to provide (in particular) uninterrupted delivery of services using available resources using all networked devices, links, and the web. The servers are on. An average improvement of 23-53 % was observed using the round-robin forwarding strategy.
