Telcos seek differentiation through network capacity addition, service quality and coverage improvement. Network Functions Virtualisation (NFV) promises to immediately lower the capital and operational cost base. This will set the scene or faster “software-defined network” (SDN) additions which will improve utilisation of network assets.
Software-Defined Networking (SDN) removes the limitations of current network infrastructures by separating the control plane from the data forwarding plane. Networks can be managed more cost-effectively and autonomously through centralising decision-making and programmability.This opens up markets for infrastructure providers to provision and offer network resources on-demand to multiple tenants and for service providers to develop and deploy their services on shared infrastructure resources cost-effectively.
