Why each option
SDN separates the control and data planes, enabling programmability and centralized automation that reduces both capital and operational costs while accelerating innovation through open APIs.
Redundancy is an architectural design choice independent of SDN - SDN does not inherently add physical or logical redundancy to the network.
SDN moves toward centralized management via a controller, which is the opposite of decentralized management.
SDN does not inherently reduce latency - in some cases the controller round-trip can introduce additional delay for flow setup.
SDN exposes network programmability through open APIs and abstracts hardware, allowing developers and operators to rapidly prototype and deploy new network services and applications that traditional hardware-locked networking cannot support.
By centralizing control and enabling automation, SDN reduces OpEx through lower manual configuration overhead and reduces CapEx by allowing commodity hardware to replace expensive proprietary appliances.
Meeting high traffic demands is a function of bandwidth provisioning and QoS, not a primary benefit of SDN architecture.
