Traffic management is still the primary use case for DPI technology, but we’re seeing a growing interest in folding DPI into larger solutions, such as video optimization, content caching, and usage-based billing,” notes Shira Levine, directing analyst for service enablement and subscriber intelligence at Infonetics Research. “This ‘DPI inside’ approach provides operators with the visibility into network traffic needed to enable new service models and pricing plans and to support new architectures like software-defined networks (SDNs).”
Some other key points:
- DPI product revenue is on track to pass the $600-million mark this year
- Mobile operators are deploying DPI hand-in-hand with LTE for more granular traffic management and to enable value-added services, tiered services, and sophisticated pricing models
- Infonetics expects operators to push DPI deeper into the access network and eventually to the device level via enforcement agents that enable greater network and service control on smartphones, tablets, and set-top boxes
