DPI Vendors Deliver on Policy Management
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.

DPI Vendors Deliver on Policy Management details and analyzes leading DPI and policy management system vendors, along with the components they are using, DPI and multicore processor vendors, and DPI and policy management software vendors. The report profiles 21 vendors in this important market, including a review of component architectures, identifying the key features and highlighting the advantages they hold for equipment manufacturers.

Network operators must ensure they obtain the best return on their infrastructure investment and provide the best services to attract and retain subscribers. Policy management is key to achieving these objectives and is being implemented on both fixed and mobile networks. Policy control is now embedded in the wireless network architecture. The following excerpt shows the 3G/LTE wireless network architecture, including RAN, packet core and connection to IMS and the Internet. The RAN includes the HSPA NodeB base stations and RNC, as well as the LTE eNobeB base stations.
