Summary

In this chapter, we learned about SDN and why it is important. We reviewed the SDN controller products, the ODL history, as well as core features of SDN controllers and market leader controllers. We managed to look at aspects of SDN in detail such as BUM and flow tables and, at the end, we reviewed how the traditional concepts and protocols function in the world of SDN.

In the next chapter, we will start looking at ODL components and modules.
