Shira Levine, directing analyst for service enablement and subscriber intelligence, Infonetics Research, released an updated Service Provider Deep Packet Inspection Products report, predicting a $1.9B market by 2017 (see chart). A year ago Infonetics had a more aggressive forecast, predicting a $2.0B market for 2016 (here).
The report finds that "Service provider deep packet inspection (DPI) product revenue totaled $596 million worldwide in 2012, up 28% .. Allot pulled ahead of Sandvine in 2012 to take the overall DPI revenue market share lead for the first time; Allot also tops the wireless DPI segment, while Sandvine leads the fixed-line DPI segment"
My own calculation (here), based on public pure players reports (Allot, Sandvine and Procera - see market share below) showed 19% growth for 2012. See other forecasts here.
"The wireless segment of the DPI market is forecast by Infonetics to grow at a 33% CAGR from 2012 to 2017 .. DPI will eventually move from core and access networks to device themselves so that operators can better manage signaling traffic, provide mobile security, and enable more granular subscriber controls such as parental control and shared data plan device control"
