Procera Offers DPI-based Carrier-Grade Network Address Translation (CGN) and Advanced Traffic Steering

Procera Networks
introduced new Carrier-Grade Network Address Translation (CGN) and Advanced Traffic Steering capabilities that leverage the subscriber, service, and application awareness of the company's PacketLogic solutions.



This marks Procera’s entry into the Application Delivery market, which represented a $2.6 billion market in 2011, according to the International Data Corporation (IDC).



Procera said its PacketLogic products simplify large-scale subscriber deployments for network and cloud service providers.



Carrier-Grade Network Address Translation (CGN): Network operators are increasingly using CGN to combat IPv4 address exhaustion. CGN is also commonly implemented on router platforms that were not designed to have subscriber or stateful awareness. The PacketLogic CGN uniquely provides these capabilities due to tight integration with the PacketLogic Subscriber Manager, which is used to simplify address management for operators, maintain subscriber visibility and service awareness, and ensure a transparent experience for subscribers.



The PacketLogic CGN solution offers asymmetric traffic handling using FlowSync, providing operators with more flexibility in CGN deployments and maintaining flow state – even in geographically diverse deployments. A CGN deployment with PacketLogic ensures that an operator maintains complete capability to leverage 3GPP policy and charging as well as full analytics and network visibility, which can be lost when deploying CGN solutions not based on IPE.



Application and Subscriber-Aware Traffic Steering: Unlike traditional load-balancing systems, intelligent policy enforcement-based traffic steering solutions can make policy decisions based on subscriber service plans and applications without complicated configurations or integrations. The PacketLogic Advanced Traffic Steering can steer traffic at any point in the flow setup process, using Procera’s unique DRDL technology to surgically send only the exact application traffic to Value Added Services solutions (VAS). This technology enables flexibility for value-added services that require full TCP-state visibility, such as video optimization or parental control, and saves significant capital and operational expense by drastically reducing the amount of hardware needed to offer VAS. Cloud operators can take advantage of the traffic steering capabilities while providing detailed charging and analytics to their customers using a single system, thereby reducing the cost, overhead, and complexity of multi-system deployments.



Advanced Traffic Steering and CGN are both available for customer trials immediately, and will ship in the third quarter of 2012. http://www.proceranetworks.com
