The History of Highly Adaptive and Programmable Networks

This chapter explores the evolution of computer networks from closed data transmission systems to complex, programmable infrastructures critical to modern life and industry. It highlights the growing demand for flexibility and adaptability in networks due to diverse and unpredictable application requirements. Key enablers of this are the concepts Software Defined Networking (SDN), Network Functions Virtualization (NFV), and programming concepts for processors as well as reconfigurable hardware. The chapter delves into the importance of network programmability in meeting future network demands, providing a foundation for understanding the terminology and applications of softwarized networks.
