The book explains the considerable features of the OpenStack components. From load balancing to routing to firewalls and others. From your previous experience with any network tasks, you should recognise the importance of these topics. The narrative also places emphasis on virtual machines. So packages like LinuxBridge are used to connect VMs. And you have VLAN interfaces. All this and more are a refactoring of tasks made possible within OpenStack.
Maybe the oldest idea in the book is VPN - virtual private network. This was first used in the 90s, predating OpenStack by several years. Then, a VPN was used to connect two or more machines into a single network that actually spanned at least 2 physical networks. But typically, those machines did not have virtual machines on them. Now the book shows how VPNs have been generalised to include the latter.
In terms of scaling, the book explains how to use a virtual load balancer. This acknowledges the need in actual industrial deployments for heavy duty task loads.

If you are using or thinking to use OpenStack to deploy more than 10 servers, and would like to understand the networking component, Neutron, deeper than the web interface allows, this is the book for you.
No need to know cisco or juniper commands, just recipes to turn visio network diagrams, with routers, lans, vlans, load balancers and subnets in to neutron commands. Perfect for automation! I found a good guide on deploy networking in a virtual data center, and the warning notes on some bugs or missing features in the openstack releases are also important to keep one out of the sandpits.
The only drawback is that the releases covered are Havana and Icehouse, and the plugins are the openvswitch and linux bridge. No commercial plugins and no ML2. I don't think the reader will miss those; if you do, you have gone trough the level of the book already,
But the advantage of this books is to get yourself up and running in a week, and that it does, at the price of being useful for 12 to 18 months, at most, giving the quick pace of OpnStack development. Five starts for the effort and dedication of the author to put together the useful information knowing that it will age quickly.
By the way, if you happen to be in the Paris summit, and can get a copy of the book, do it. You will learn a lot and wont regret it.
This is the 1st book dedicated to Networking in Openstack, that's why I have pre-ordered it as soon as I see it. Author is a real time development engineer in related area and it has advantages & dis-advantages.
Advantages: Since he is Subject Matter Expert, he does not "BS", he presents his knowledge from practice, lab-implementation side.
Dis-Advantages: Like in every engineer (including myself) who writes a technical document, Author has assumed reader is full aware what is going on behind the scenes; such as "Openflow rules within OVS", such as usage of Neutron L3 Agent may cause bottle neck for high bandwidth traffic and it is a single point of failure.
I recommend this book to new beginners of Openstack to learn little bit more about Neutron and have a general idea about forthcoming fancy features...
I am looking forward for 2nd Edition with wider & deeper coverage.
Ps; Ready to pay more for more knowledge :-)
