SDN blog roundup: Open Daylight, Cisco's networking truths, OpenStack

SDN bloggers discuss the launch of OpenDaylight, Cisco's three networking truths, and how SDN products are sparking interest in the channel.

OpenDaylight launch sparks debate among bloggers

On April 7, bloggers, analysts, and industry pros alike took note of the launch of the OpenDaylight Project: an open source SDN consortium that already includes heavyweights like Cisco Systems, Big Switch Networks, Brocade, Citrix, Ericsson, IBM, Juniper Networks, Microsoft and Red Hat as platinum members.  

Reactions to the launch were mixed. Roy Chua wrote on the SDN Central blog that although this is a moment "the networking industry can't ignore," the consortium is a large risk that "could still fall apart." The mix of vendors and "competing agendas" could pose a problem, and it's still unclear how a number of disparate projects can come together within a single architectural framework, he wrote.

Meanwhile SDN expert Jason Edelman wrote on his personal blog that open source SDN, if it takes off, will be invaluable to emerging companies that support open source platforms such as OpenStack. These companies will be able to use OpenDaylight contributions to help enterprises of all sizes build and adapt to SDN environments.

In another critical look at the project, blogger Ivan Pepelnjak wrote that at the end of the day, an open source SDN controller supported by all major networking vendors sounds "almost too good to be true," and he's certain there will be "some posturing, bickering and backstabbing in the Daylight's future."

Cisco tackles the 'truths' about networking

According to Cisco CTO Padmasree Warrior, the current SDN debate, albeit "healthy," has created confusion around the concept of software-defined networking. While in some circles, SDN has "become synonymous with the erosion of value in the underlying network infrastructure -- the hardware and the ASICs," that's simply not the case, Warrior wrote on the Cisco blog.

Warrior broke down what Cisco sees as the three truths of the future of networking. She said that network virtualization is, indeed, different from server virtualization, and that the forces driving the adoption of network virtualization are different from those that drove server virtualization. Additionally, Warrior argues that application performance creates greater demand for physical and virtual innovation. Nevertheless, routers and switches will continue to be relevant in the world of SDN, resulting in a $670 million market for next-gen applications for Cisco. Warrior closed her post by describing how a software-only approach actually increases cost, writing that the next chapter of networking will be a systems approach that requires ASICs, hardware and software to all work together.

Using DevStack in an OpenStack Grizzly Install

On his Network Static blog, Brent Salisbury broke down the networking side of OpenStack and described in detail installing OpenStack Grizzly with DevStack. The process is "pretty painless," he writes, and with the release of Grizzly to occur at the OpenStack Summit in the coming weeks, developers should take note.

DevStack, Salisbury writes, is a "handy tool," while OpenStack Grizzly has a number of new features, including security groups, floating IPs in Horizon, and Open vSwitch and NEC OpenFlow plugins.

Check out Salisbury's steps to installing OpenStack Grizzly with DevStack.

SDN brings together the channel and enterprise networking

On the site Channel Insider, blogger Michael Vizard wrote about the channel's growing interest in SDN products. According to Vizard, SDN is key to networking channel growth but the challenge comes when solution providers must decide which SDN route to take.

Vizard described two SDN technology strategies: a hardware-centric approach and a software-centric approach. He listed a number of vendors who have taken one of the two approaches and outlines the benefits of each. He ended his post by reiterating that SDN is one of the most disruptive events to occur recently in enterprise networking. "The challenge facing solution providers is figuring out how to educate customers about SDNs in a way that does more to expand the market," he wrote.

Companies confused about SDN but still want it

According to a recent post by Steve Wexler on the IT-TNA IT Trends and Analysis site, nine out of 10 organizations are considering SDN, yet they're still fairly confused as to what it actually is. A survey from Tail-f Systems looked at more than 200 large North American companies and found that SDN was viewed as the single most important technology initiative, beating out cloud, virtualization and mobility.

Wexler went on to detail what respondents were looking for in terms of SDN deployment and some of the challenges associated with the technology. He said despite the confusion concerning what SDN actually is, many respondents were "crystal clear" on what they were hoping to get from the technology. Much of this interest in SDN stems from boredom with existing solutions; people want to do what they're doing now but more quickly, with automation and fewer errors, he wrote.
