What network topologies can I build with Openstack Quantum server

The Folsom Openstack release brings many enhancements to networking stack in the Openstack version of the cloud. The features have been encapsulated with in a new core project called Quantum. But even looking at the documentation it can be very difficult at the beginning to understand what are the differences to old nova-network solution and how an example Quantum virtual network can be configured.

Fortunately there is an easy to follow video introduction to Quantum from last Summit [1]. The slides to it can be found here as well [2].

Below are example slides from the presentation of how a virtual network can be build and how it can look like in cloud powered by Openstack, examples: single flat network, multiple flat networks, mixed flat plus private networks, single provider network, multiple per tenant private networks plus single provider network.
