Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." [82][83], Quality of Experience (QoE) estimation using SDN. Second, businesses can leverage SDN controllers to improve the functionality of campus networks, which are often complex due to ongoing Wi-Fi and Ethernet needs. Distributed applications that run across datacenters usually replicate data for the purpose of synchronization, fault resiliency, load balancing and getting data closer to users (which reduces latency to users and increases their perceived throughput). To estimate the QoE, first we have to be able to classify the traffic and then, it's recommended that the system can solve critical problems on its own by analyzing the traffic. With network virtualization, organizations can open the door to greater efficiency through new tools and technology, such as Software-as-a-Service (SaaS), Infrastructure-as-a-Service and other cloud computing services, as well as Businesses that invest in SDN are often lured in by its ability to support data-heavy applications.
