bility of the complete network with decision making authority and all the hardware simply forwards the packets based on the controller's Instructions. Software Defined Networking is changing the way we design and manage our networks. Data Plane has been completely separated from the Control & Management Plane of the controller (Darabinejad, Rasoul, Fayyeh, 2014). This open source controller can be managed with our own customized software on the well defined Application Programming Interfaces (APIs) called as Northbound APIs (Xia, Wen, DOI: 10.4018/978-1-5225-3640-6.ch006 Copyright © 2018, IGI Global.

These are the specific APIs that are opened from the controller to be managed with the customized software and it pushes the configuration further to the devices that the controller manages with its southbound APIs. Devices will no longer be configured or Managed with their local management. It is all done by the controller in a programmatic way, not prone to human errors. Time to Provision Applications, Configurations, deployments tasks have been reduced from days to minutes. SDN is also an answer to the Rapid changes to the network configurations through the predefined scripts and with the customized scripts for our customized tasks (Programmatic Approach to configurations). There is a lot of administrative overhead to the overall datacenter and still there is a chance to configure at least one of the datacenter device incorrectly as the configuration & Implementation need proper planning of the overall network. SOME OF THE SDN REAL WORLD BENEFITS IN TODAY'S IT Rapid reconfiguration of the devices. Abstraction of the Infrastructure. Automation & Orchestration. Devices Programmability. Application level Enhanced visibility. Handling unpredictable traffic Patterns. Centrali
