The rate at which telecom networks are growing and changing is nothing short of fantastic. It’s always risky to embrace a new paradigm, but for network carriers and customers, the risks of waiting could be greater.
Network function virtualization (NFV) and software defined networks (SDN) represent a radical departure from the traditional way of building, managing and evolving telecom networks. It’s often described as a switch from proprietary boxes to commercial-off-the-shelf (COTS) hardware. While there is a potentially significant cost-savings in making such a switch, cost-savings is not the main driving force. The ability to quickly implement new business models, to deliver applications on demand, and to automatically provision and tear down resources are what make NFV and SDN so potentially disruptive.
