SDN, or Software-Defined Networking, is an approach to network management that enables dynamic, programmatically efficient network configuration in order to improve network performance and monitoring. It is a way to approach networking that allows network administrators to manage network services through abstraction of lower-level functionality.

Here are the steps to understand SDN:

1. Traditional networks require manual configuration and are complex to manage. They are also inflexible, meaning they can't easily adapt to changing business requirements.

2. SDN separates the network's control (brains) and forwarding (muscle) planes to make it easier to optimize each.

3. The SDN controller acts as the brains of the network. It provides a centralized view of the network and allows administrators to dictate to the underlying systems (like switches and routers) how the networking should flow.

4. This allows for more automation and programmability in the network, which can lead to better performance and efficiency.

Advantages of SDN:

1. Centralized network provisioning: SDN provides a centralized view of the overall network, which makes it easier to provision, monitor, and manage network resources.

2. Reduced complexity: By abstracting the control and data planes, SDN simplifies the network design and operation.

3. Better alignment with cloud principles: SDN supports automated, programmable networks, and it aligns well with cloud environments which demand dynamic, scalable, flexible, and efficient networks.

4. Improved network management: SDN enables network administrators to manage network services through abstraction of lower-level functionality. This simplifies the network design and operation.

5. Increased innovation: SDN allows organizations to create new types of applications, services, and business models that can offer more revenue streams.

6. Cost efficiency: By using commodity hardware and reducing manual tasks, SDN can significantly reduce CapEx and OpEx costs.
