Software-Defined Networking has been one of the most talked about topics in the field of networking in recent times. It is a new approach to designing, building and managing the configuration of network devices. The traditional approach of networking has largely been hardware centric and the functionality is implemented in the network devices i.e. gateways, switches and routers. These traditional networks require human efforts to administer the hardware configuration process, which is rigid and inefficient. In addition to the management of network devices, the routing decisions are taken at individual devices which may not have information about the global status of network, this often results in sub-optimal routing decisions. A promising solution to these problems is switching to software-defined networks, in which the required configuration and management of the devices can be done through a software interface.In this report, we study the technological landscape of this fast growing technology from an Intellectual Property (Patents) perspective.
