Performance Analysis of Software Defined Network with Three Controllers

Software-defined network is one of the best methodologies of computer network that countenances to an administrator to succeed the computer network amenities through the perception of subordinate side by side functionality. Software-defined network (SDN) is alienated into two fragments: one is Control plane and former is Data plane. In control plane are the actually deployed devices. This control plane is located at a fundamental controller. The controller is responsible for building the forwarding base and figuring out how a packet should be forwarded through a network. The SDN controller takes the information of packages and places it in a forwarding table or flow table of devices, the controller verifies the protocol made by the administrator and forward the packet to the router. In this paper, the performance analysis of SDN is done with the help of one, two and three controllers and will see how much the transfer time is affected with increasing number of controllers.
