SDN Simulation Tools

What is SDN?

The software defined networks are denoted as the evolution in the field of networking and the data plane is detached from the control plane with all the controlling process. Additionally, the centralized controller is used to process the tasks based on management. The environment of software defined network includes three significant planes such as,
