This chapter researches in the area of software-defined networking. Software-defined networking was developed in an attempt to simplify networking and make it more secure. By separating the control plane (the controller)—which decides where packets are sent—from the data plane (the physical network)—which forwards traffic to its destination—the creators of SDN hoped to achieve scalability and agility in network management. The application layer (virtual services) is also separate. SDN increasingly uses elastic cloud architectures and dynamic resource allocation to achieve its infrastructure goals.
