The document discusses the benefits of software-defined networking (SDN) and network functions virtualization (NFV) over traditional network architectures. SDN and NFV allow for reduced costs through more efficient hardware usage, centralized management, and virtualization of network functions. They also provide greater agility by making networks easier to scale, automate, and migrate resources. The CTO explains how SDN and NFV are already widely available technologies being used by major vendors, and how their implementation was crucial to the success of Hutchinson Networks' own SDN-based "Fabrix" platform by reducing costs while improving scalability and orchestration capabilities.
