SDN Market Expected to Grow 65 Percent in 2014


October 16, 2014

A new report by Dell’Oro Group has found that the Software Defined Networking (SDN) market is expected to grow by 65 percent in 2014.

The company has outlined its findings in the report titled “2014 Data Center Disruptors Advanced Research Report.”

The Ethernet switch market is undergoing a technological transformation in the data center, driven by changes in data center networking. “It is clear that, by 2020, data centers will look significantly different from today's,” said Alan Weckel, vice president at Dell'Oro Group.  "How users access data centers will be forever changed, as will the way enterprises deploy and manage them, and the vendors that operate in this market.”

A lot of this growth is being driven by the deployment of faster Ethernet, with speeds of 10 gigabits and 20 gigabits per second. Most of the growth will come from network security appliances and Ethernet switches.

“The evolution towards 10 GE in the Enterprise and 25 GE in the Cloud is an opportunity for data center vendors and providers to garner an increased amount of IT spending, with vendors and providers that understand and embrace the technology change to virtualized data centers running at 10 GE or higher speeds having the opportunity to see their shares of IT spending increase and their market positions improve in the next several years," Weckel said.

The adoption of SDN in data centers is a logical extension of the drive toward virtualization that’s also happened in recent years. Rather than dedicating single servers to functions such as databases or email servers, it’s easier and often cheaper to host different virtual servers inside a single physical machine.

SDN lets IT staff use decouple the logical network from the physical network. Just as physical servers can host different virtual servers, administrators can define virtual networks independent of the actual physical connections. The control of the network is centrally managed across an entire organization rather than spread out across servers and switches.

This centralization will make SDN more valuable to organizations with large networks trying to manage complex traffic patterns.

Day 2, Cisco Live! 2017

Tuesday was Day 2 of Cisco Live for Fiber Mountain and we continued to experience high levels of traffic, with many high value decision makers and influencers visiting our booth. One very interesting difference from most conferences I attend is that there are no titles on anyone's show badges. This allows open conversations without people being pretentious. I think this is a very good idea.
