As networks become "all-IP" and usage billing becomes more prevalent, the need for functions, such as fast address look up, forwarding and Deep Packet Inspection (DPI) become critical in many network elements. Scaling the capacity of these network elements hinges on having the right capability to perform at wire-speeds. The ATCA-7240 enables exactly these capabilities to reduce cost per bit and power consumption while accelerating TEMs time to market when utilizing the Radisys ATCA platforms.

The new solution further extends the capabilities of the ATCA-7240, a full-duplex 40G packet processing module that provides a complete line-rate solution for applications, such as serving gateways, session border control, security gateways, DPI, edge routers, media gateways and mobility management entity network elements found in 4G LTE evolved packet core.

Radisys revealed that the ATCA-7240 has the ability to offload L2-L4 access control list and longest prefix match lookups in a deterministic fashion from the data processing blocks, thereby accelerating complex search requirements. The product is ideal for high-speed networking applications, such as packet classification, access list control and intrusion detection, according to the company.

As part of the Radisys ATCA 4.0 platform, the ATCA-7240 network search engine also inherits the benefits of the Radisys integrated platform, including reduced time-to-market, cost and development risk-valuable benefits in the migration to 40G. Supported by Radisys' product and partner ecosystem, which provided validation and support across all solutions, TEMs can be assured of forward and backward compatibility as they migrate to 40G platforms from Radisys.
