‘Thought Cisco’s SDN strategy was a mess? You weren’t alone. It’s still complex, but Cisco has honed down its message to one where SDN reigns and policy looms over all. Step one: grouping products together and selling them like software.
The SDN machine is making good progress, but: Enterprises don’t get it, ordinary data centers need better use cases, and there’s a lack of success stories that don’t sound like superhero feats. How quickly can SDN spruce itself up for the mainstream?
More than a token SDN movement, AT&T’s Domain 2.0 is about ‘radically reshaping the entire wide-area network,’ as keynoter John Donovan told the Open Networking Summit. He wants to see quick changes, and he’s not kidding around.
OpenFlow 2.0 doesn’t exist yet, but Nick McKeown, Jennifer Rexford, and other researchers have crafted their vision of what it could be. It involves even more flexible switches that Barefoot Networks is trying to invent, and Stanford is looking at how to make it all work.
The ONF is announcing its first app — but not for the sake of going into business. As Dan Pitt will explain at the Open Networking Summit, the ONF’s network tap is a good, non-invasive way to give operators hands-on experience with OpenFlow and the OpenDaylight environment.
The OpenFlow 1.3 tide is going to be strong this year and especially this week, as the Open Networking Summit convenes. Brocade is announcing its OpenFlow 1.3 support, but — in what’s likely to be a trend — it isn’t supporting every feature just yet.
NEC continues to plug away at advancing its OpenFlow software, this time creating the Unified Network Coordinator to manage 10 OpenFlow controllers as one. It’s arriving with new ProgrammableFlow software being shown at the Open Networking Summit.
From Mobile World Congress, a chat with Sanqi Li, CTO of the carrier network business group, about the scaling challenges of SDN, the motivations for NFV at the edge, and the contrasts and similarities between data center and carrier networks.
The Brocade SDN army continues to grow. The latest recruit is Kevin Woods, who headed up Cisco’s onePK initiative and helped organize the company’s cross-department SDN strategy.
At Mobile World Congress, little-known startup Affirmed Networks got a surge of attention after being picked by AT&T to work on the LTE evolved packet core (EPC). It turns out Affirmed is further along in this work than you might think.
