IPv6, SDN: When worlds collide ... in a good way
This article is part of the Network Evolution issue of December 2013 Vol. 4 / No.6
What do IPv6 and software-defined networking have in common? Not a lot, but then again, oh so much. Both IPv6 and SDN stand to radically change the way we build networks, and if implemented correctly, both play a role in making the cloud and IT as a Service more of a reality. In the last five years, server and storage virtualization have revolutionized IT, enabling flexible provisioning of resources that can be used for an agile cloud. But the rigid network has been a bottleneck. Now, SDN promises to virtualize the rest of the data center infrastructure and make it so that network resources can be provisioned on demand and integrated into overall cloud orchestration. Meanwhile, as IPv4 addresses become rapidly depleted, service providers and enterprises are under pressure to transition their networks into IPv6 environments. Here is where SDN and IPv6 implementation meet. If both sets of technologies require network teams to rethink network design, why not do both at once? The good news is that these two technology trends can be ...

Features in this issue
There's plenty of potential in unifying public and private cloud resources, but there are also hybrid cloud challenges that make the IT team question its role.
A number of enterprises are moving beyond premises-based UC hardware, choosing cloud-based UC technology for reasons as varied as their business models.
IPv6, SDN and the cloud seem like separate initiatives, but they are interdependent. SDN and IPv6 will enable cloud agility. The good news is they are also complementary.
Columns in this issue
Engineers need to implement major network change for IPv6, SDN and hybrid cloud. But they're learning they'll have to manage the old and the new at once.
New vendors are pushing network architectures that decouple software from hardware and run on bare metal switches with merchant silicon. Have we reached the x86 era in networking?
