Rohit Mehra, vice president of network at IDC, said that his firm predicts the total enterprise networking market for 2013 to come in at $42.4 billion. The Layer 2-3 switch market represents the lion’s share of that figure at 46.9 percent. The market for Layer 4-7 devices, including application delivery controllers, is growing, though Mehra is more impressed by the pace of WLAN growth. He noted that WLAN revenues grew by 28 percent in each of the last three years.
Moving forward, Mehra said that IDC predicts the enterprise networking market to exceed $50 billion, with growth across all categories, by 2017.
One of the most exciting categories to emerge in recent years is the Software Defined Networking (SDN) space. IDC forecasts that by 2016, the in-use SDN marketplace will generate $3.7 billion in revenue. That’s the same figure that IDC forecast for the SDN market in December 2012. At IDC’s Interop 2012 breakfast meeting earlier that year, the firm pegged the 2016 market at $2 Billion.
