NetLogic Microsystems and Wintegra announced a collaboration between the companies to develop an application-intelligent deep-packet inspection (DPI) reference solution targeted at next-generation 4G/LTE (Long Term Evolution) and HSPA+ wireless base station and aggregation backhaul systems. The reference solution incorporates Wintegra’s WinPath access packet processors and NetLogic Microsystems’ NETL7™ Layer 7 knowledge-based processor, and enables mobile operators to perform real-time DPI to effectively manage services, bandwidth, per-subscriber quality of service (QoS) and security of their networks.
The growing consumer adoption of intelligent handsets and mobile video phones is creating new demands on the mobile wireless infrastructure. While the world’s leading carriers are rolling out high-speed LTE (Long Term Evolution) wireless broadband services, existing deployments of 3G networks are being upgraded to HSPA+ capability and are quickly becoming swamped with peer-to-peer (P2P), video streaming, voice-over-IP (VoIP) and gaming traffic, and are susceptible to the same type of aggressive network security attacks that afflict traditional wireline broadband networks. Deep-packet inspection technology provides an effective solution that enables operators to make efficient use of available network resources, to deploy tiered service plans that differentiate between premium and best-effort services, to enhance ROI, and to reduce security threats on the network as well as mobile devices. These capabilities can be rolled forward into LTE designs with software and performance upgrades offered by Wintegra and NetLogic Microsystems.
The collaborative reference design from NetLogic Microsystems and Wintegra offers operators and original equipment manufacturers (OEMs) the ability to perform comprehensive and real-time DPI in the base station and access aggregation equipment without compromising the overall network throughput or extending system latency while at the same time offering significantly lower power consumption when compared to competitive solutions. Given the existing deployments of Wintegra’s market-leading WinPath solution in mobile access networks, vendors can quickly upgrade their networks to add these important capabilities.
Wintegra’s WinPath family comprises advanced packet processors with up to twelve protocol-processing engines specifically optimized for data plane processing functions in advanced mobile wireless infrastructure equipment. The highly optimized packet engines offer significantly higher performance and lower power consumption for next-generation HSPA+, LTE and WiMAX systems. The multi-protocol functionality and internetworking features of the WinPath processor family, combined with carrier-grade, production protocol software from Wintegra, enables operators to seamlessly migrate from today’s ATM and TDM networks to IP networks while minimizing costs, time-to-market, power consumption and footprint.
”Leading wireless operators and service providers recognize the need to enable deep packet inspection in their 4G/LTE networks to maximize the return on their infrastructure investments, and are seeking robust, cost-effective solutions to help them manage and secure their networks,” said Michael Phillip, senior vice president and general manager of Wireless Systems at Wintegra. “We are excited to partner with NetLogic Microsystems on their best-in-class NETL7 processor which, in conjunction with our industry-leading WinPath access processor, provide customers with a scalable DPI solution for advanced base stations and access aggregation systems.”
NetLogic Microsystems’ NETL7 knowledge-based processor family comprises highly scalable solutions that are optimized to accelerate computationally intensive DPI functions in real time. By offering customers seamless scalability in hardware performance from 250Mbps to 20Gbps with a common set of APIs and software development kit (SDK), the NETL7 processors enable wireless infrastructure OEMs to develop a wide range of systems, from base stations and NodeB equipment to access aggregation and gateway solutions. The NETL7 processors integrate NetLogic Microsystems’ Intelligent Finite Automaton (IFA) technology which delivers significant performance, power and cost advantages, and natively perform stateful cross-packet inspection in hardware. In addition, the NETL7 processors integrate on-chip memory and provide over 100 Terabits per second (Tbps) of ultra-low latency access bandwidth to on-chip rule databases to effectively accelerate complex and iterative content inspection, while eliminating the need to provision for the high-latency and costly off-chip memory that are required by competing solutions.
”We’re pleased to have collaborated with Wintegra to develop a reference solution that includes best-in-class technologies from both our companies,” said Chris O’Reilly, vice president of marketing at NetLogic Microsystems. “Because the WinPath and NETL7 processors are highly optimized for data path and DPI content processing, respectively, we believe that our joint reference solution offers customers the highest performance, lowest power consumption and lowest latency relative to any competing solutions.”
The collaborative reference solution includes software development kits (SDKs) for Wintegra’s WinPath processor and NetLogic Microsystems’ NETL7 knowledge-based processor. The Wintegra SDK includes C-language sources and an API for driver interface code (WDDI) for all WinPath features, as well as an optional Wintegra DPS Development Kit (WDDK). The WDDK provides production-ready data path source code for key base station, backhaul and aggregation protocols and a tool suite consisting of a compiler, linker, debugger and performance analysis tools. NetLogic Microsystems’ NETL7 SDK includes a high-efficiency rule compiler that has been validated against leading real-world DPI databases and network traces, thereby providing customers with a highly robust solution for carrier-class applications.
