For this review, DPI is defined as the network equipment used for traffic control on public networks using DPI primarily to identify traffic and match it with a bandwidth allocation policy (see more here). This is the most common use of DPI today, deployed to handle traffic congestion and reduce bandwidth costs. In some cases, the vendor’s DPI offering is derived from an OEM or partnership agreement.
The analysis does not refer to other uses of DPI, such as charging functions (to be found mainly in GGSN offering), behavior analysis and other content based services.

Note that not all revenues of these companies come from the ISP/Carrier markets, as they sell traffic control solutions to the enterprise and education markets as well.
