One way of dealing with these threats, is the use of Deep Packet Inspection (DPI). DPI is a technology that monitors the payload content of IP packets being transmitted across a network. The payload contains the application layer data i.e. the actual user data that is being transmitted. In a nutshell, what DPI does is to provide network visibility and maintains the security and integrity of networks.

The rapid growth in mobile data networks is proving to be a huge opportunity for DPI and policy enforcement system vendors. With an exponential increase in the number of subscribers of data services, DPI is increasingly gaining popularity with service providers to make the network application aware. Mobile operators are also turning to DPI in order to monetize as well as control mobile data traffic. Though traffic management is the main use of DPI, there is an increasing level of interest in other applications such as new service and pricing models, video optimization and software defined networks (SDN). Some of the key players in this market include Allot Communications, Procera Networks, Inc. Sandvine Corporation, Arbor Networks, and Cisco Systems.
