Especially confusing to many is the difference between these kinds of cloud networking services and the increasingly discussed OpenFlow open-networking protocol.
In part 1 of this series, I described what is becoming an increasingly ubiquitous model for cloud computing networks, namely the use of simple abstractions delivered by network systems of varying sophistication. In part 2, I then described OpenStack's Quantum network service stack and how it reflected that model.
