Which deployment model provides vertical partitioning by assigning certain resources in the switch or router to be controlled by the OpenFlow controller?

• A. Reactive Mode—Integrated
• B. Proactive Mode—Ships-in-the-Night
• C. Hybrid OpenFlow—Integrated
• D. Hybrid OpenFlow—Ships-in-the-Night

Answer: (D)

The Hybrid OpenFlow—Ships-in-the-Night model is appropriate for providing vertical partitioning because it allows specific resources on a switch or router to be managed dynamically by an OpenFlow controller while also enabling traditional networking protocols to function concurrently. This deployment model combines the flexibility of OpenFlow with the stability of existing network protocols, facilitating a seamless integration where both can operate without interference. In this context, vertical partitioning refers to the capability of separating specific flows or traffic types and assigning them to be controlled independently by the OpenFlow controller. This is particularly beneficial in environments where some existing services must remain operational while introducing programmability through OpenFlow. When utilizing this model, network operators can choose which parts of the network are managed by OpenFlow and which remain under traditional control, enhancing the network's agility and responsiveness to application demands. Thus, it effectively supports segmented control of network resources in a way that aligns with modern network architecture goals.
