Questions & Answers

Q: What is software-defined networking (SDN)?

SDN is an architecture that separates the network control plane from the forwarding plane, facilitating programmable network control and adaptable infrastructure. It allows for efficient management and optimization of network resources.

Q: How does SDN enable programmable network control?

SDN decouples the network control function from the hardware, allowing network operators to directly program the behavior of their network using software applications. This enables the customization of network behavior to support new services and individual customer needs.

Q: What is the role of the OpenFlow protocol in SDN?

OpenFlow is a programmable network protocol that facilitates communication between OpenFlow switches and controllers in an SDN environment. It separates the programming of network devices from the underlying hardware, providing a standardized and centralized approach to network management.

Q: What are the advantages of using OpenFlow switches in SDN?

OpenFlow switches enable enhanced traffic management and engineering by decoupling the control functions from the hardware they control. They allow for efficient routing, load balancing, traffic isolation, network tapping, and the development of new services and features.

Summary & Key Takeaways

• SDN is an architecture that separates the network control plane from the forwarding plane, allowing for programmable network control and adaptable infrastructure.

• SDN enables network managers to configure, manage, secure, and optimize network resources quickly and efficiently.
