Can SDN control certain types of traffic to be sent first, and certain types of traffic to be sent later?
Dear Tiange Xiang,
in SDN switches according to the OpenFlow Specification, the individual Flows can be assigned different Priorities. This should (theoretically) enable the Prioritization of Data Flows.
See in OpenFlow Switch Specification

especially.

Dear Professor Anatol Badach
I want to classify the traffic in SDN, and then transmit the classified traffic according to the class priority (for example, video traffic is transmitted first, and then download traffic. Of course, this traffic has been classified by traffic) or first specify a kind of traffic Transmit (for example, video traffic) and then transmit other traffic. Is it feasible?
Thank you
