A company plans to develop an SDN application in-house. The application will implement complex policies that make forwarding decisions, as well as set priorities and rate limits for various types of traffic. How can OpenFlow 1.3 accommodate these actions?
A. Only the actions applied in the last table to which a packet is matched take effect, so flows in the highest numbered table must specify all desired actions.
B. The application must define groups, which consist of multiple actions. Flows then specify those groups in forwarding actions.
C. Flows must be added to a software flow table in order to accommodate complex flows with multiple actions.
D. Packets can be matched against multiple flow tables, accumulate a different type of action from each matching flow, and execute all actions as a set.
