The white paper highlights how Software Defined Networking (SDN) and Network Function Virtualization (NFV) are reshaping telecom by replacing hardware-centric systems with software-driven models. Benefits include faster service activation through virtual testing, scalable monitoring with software-based agents, cost efficiency from leveraging non-proprietary platforms, and open architectures enabling interoperability. Challenges include integrating legacy networks and ensuring strong assurance functions. A proof-of-concept showed automated multi-carrier provisioning, with virtual test agents detecting packet loss invisible to basic checks. Ultimately, SDN/NFV supports proactive monitoring, reduced costs, and innovative service models bridging legacy and virtual networks.
