Software-defined networking(SDN)technology is an approachto(71)management that enables dynamic,progranmatically efficient network configuration in order to improve network performance and monitoring,in a manner more akin to(72)computing than to traditional network management. SDN archi tectures decouple network control and forwarding functions,enabling the network control to become directly(73)and the underlying infrastructure to be abstracted from applications and network services.SDN was commonly associated with the (74)protocol since the protocol's emergence in 2011. When using an SDN based model for transmitting multimedia traffic,an important aspect to take account is the(75)of Experience(QoE)estimation.To estimate theQoE,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.
