The rapid growth of broadband in both fixed and wireless networks has made policy management a critical element of any network infrastructure. The policy enforcement needed for policy management requires advanced deep packet inspection (DPI) solutions that can identify applications within the traffic flows at rates in excess of 100 Gbit/s.
First-generation DPI solutions were hardware devices that could identify a small number of patterns within individual packets. Policy management systems for wireless and wireline networks require stateful analysis of packets within a flow and the application of many signatures to multiple packets within a flow. In addition, data rates have grown significantly and signatures must be updated regularly. To meet these requirements system and software vendors have switched from hardware based solutions to software running on multicore processors.
Policy management is becoming a core requirement for broadband service provision. The current market is dominated by specialist vendors with DPI and policy enforcement software that will run on a range of multicore processors. By using standalone policy enforcement systems, operators have been able to deploy policy management solutions independently of the core network infrastructure.
Most policy management vendors now offer software solutions that will run on any of the leading multicore processors. As shown in the report, there is now a strong software ecosystem, and new multicore processors are becoming available that will deliver significant increases in performance. This gives operators the opportunity to deploy policy management solutions using the most appropriate software functionality and the hardware platform that best fits with their network infrastructure.
