An architecture based on SDN techniques gives operators greater freedom to balance operational and business parameters, such as network resilience, service performance and QoE against opex and capex. The traditional way of describing network architecture and how a network behaves is through the fixed designs and behaviors of its various elements. The concept of software-defined networking (SDN) describes networks and how they behave in a more flexible way - through software tools that describe network elements in terms of programmable network states.
