Summary
In this chapter, we talked about how programmable networks have evolved up until the present day. We discussed the history of data plane and control plane separation. We’ve seen how network virtualization has improved over time. We also looked at some technologies and standards for SDNs and cloud networking, such as OpenFlow and OpenStack.
You now have the knowledge required to understand why some technologies are used today to automate and code networks.
In the next chapter, we’re going to dive deeper into the methods, protocols, and standards used to configure and communicate with network devices.
