Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) have fundamentally changed the networking industry by separating the control and data planes, which facilitates dynamic network management and enhances resource efficiency.These technologies have initiated a significant transformation in network architecture and operations.By decoupling the control and data planes, SDN and NFV offer unprecedented levels of flexibility, agility, and efficiency in network environments.This shift allows organizations to manage their networks dynamically, maximize resource utilization, and swiftly adapt to changing business needs.This research paper examines the latest developments in SDN/NFV architectures and routing solutions, discussing key concepts, challenges, and innovations in these areas, and providing valuable insights for network engineers, researchers, and practitioners and also presenting a new routing algorithm suitable for this new architecture.
