IDT (Integrated Device Technology) has announced another design win for its network search engines (NSEs), as its 75K62134 NSE has been selected by Anagran for use in its Flow State Aware routers.

Key features of the NSE are its advanced search facilities, a glue-less interface to different network processing units and hardware/software development packages.

“Flow control and management become increasingly necessary in broadband networks to achieve and maintain high quality voice, video and other traffic among all end users,” said Joon Choi, director of product management at Anagran.

“The IDT 75K62134 NSE solution provides the hardware acceleration critical to meeting our performance goals while its database management feature enables significant power savings.”

The 75K62134 was the first device with a glue-less integrated Network Processor Forum (NPF) Look-Aside (LA-1) interface. It can support up to 256K IPv4 entries, and offers the ability to cascade up to thirty-two devices in order to support larger databases and enable further functionality into customers’ end boxes.

The 75K62134 also supports multiple databases for a variety of applications related to multi-field classification and is available in search widths up to 576 bits.

Anagran's routers keep state information about packets associated with individual flows, with the capability to determine duration, rate and byte count per flow. This information is critical in managing traffic flows to ensure higher levels of quality of service.

The FSA approach to IP routing represents the first significant quality improvement and cost reduction in IP since its inception and enables converging different networks into one IP-based network with end-to-end QoS enforced.

“Anagran has a relatively unique application for our NSE – a flow state aware router - and we are excited to be a part of their design,” said Dave Cech, director of marketing for the IDT IP co-processor division.

“The IDT 75K62134 NSE enables Anagran to achieve highly efficient and flexible flow management – which is becoming increasingly more important in supporting revenue generating services and support agreements via IP routing.”
