Among the OpenStack projects getting the most attention here at the OpenStack Summit Paris is the Neutron networking project.
I’ve had the opportunity to dive headfirst into Neutron over the last nine months while writing Learning OpenStack Networking (Neutron), which is available from Packt Publishing. If you were unable to receive a free copy at the OpenStack Summit, you can still get a 30 percent discount using the code “luyLRpSQ” at https://www.packtpub.com/virtualization-and-cloud/learning-openstack-networking-neutron </shameless plug>.
In Juno, the latest OpenStack release, Neutron introduces a host of new features that users have been clamoring for to achieve Nova network parity, including Distributed Virtual Routers (DVR) and High Availability routers using VRRP. These features bring high-availability to the L3 networking layer, albeit in very different ways. While both methods are considered experimental, they can reduce the “single point of failure” that was found in previous implementations of Neutron routers and can ensure consistency and reliability.
Juno also introduces additional support for IPv6. For more information, check out a proposed presentation at http://www.openstack.org/vote-paris/Presentation/ipv6-features-in-openstack-juno-release.
And that’s not all. While working on the book, we noticed that the previous walkthroughs on the Rackspace Developer site are outdated – they’re made for Grizzly and Havana. We’re working hard to update the walkthroughs and the advanced networking blogs over the next few weeks, so stay tuned. In addition, we’ll also be sharing more information as the Neutron work for OpenStack Kilo progresses this week in Paris.
It’s an incredibly exciting time to be working on Neutron, and I had the pleasure of presenting to a group of enthusiastic OpenStack operators and developers on Wednesday morning.
