The promise of Software Defined Networking (SDN) is gaining more and more attention as traffic growth increases the costs and complexity of network operations. This white paper explores how SDN-based solutions can transform today’s rigid transport infrastructure into a highly programmable network, one that is just as flexible, efficient and seamlessly scalable as data-center computing and storage resources. By deploying the right SDN-enabled solution, service providers can capitalize on the opportunity to migrate their multi-layer transport networks according to their individual business strategies and budgetary considerations to both increase revenue and lower costs.
