Dual Cavium OCTEON II CN68xx Packet Processing

The ATCA-7240, is the third-generation of Radisys packet processing products based on the Cavium Networks OCTEON family of multi-core processors.

The ATCA-7240 is a versatile full-duplex 40G packet processing module utilizing two powerful OCTEON II CN68XX processors, each with 32 cnMIPS64 cores and comprehensive hardware acceleration that provides a complete line-rate solution for applications such as Serving Gateways (SGW), Session Border Control (SBC), Security Gateways, Deep Packet Inspection (DPI), Edge Routers, Media Gateways and Mobility Management Entity (MME) network elements found in the 4G LTE Evolved Packet Core (EPC).

  • 40Gbps full duplex line rate processing
  • Up to 32GB DDR3 SDRAM per Data Processing Block (DPB)
  • Flexible data flow options with multilayer on-board switch
  • Up to 160 Gigabit Ethernet (GbE) of max port density in single-slot solution
  • Optional Network Search Engine RTM for ultra-high capacity parallel search

The ATCA-7240 with Dual OCTEON II CN68XX processors improves upon the field-proven advantages of the previous generation ATCA-7220 Dual OCTEON CN58XX by delivering up to 80 gigabits per second (Gbps) processing performance, increased memory capacity and maximum I/O density to meet industry demand for highly integrated, higher performance-per-watt solutions and provides a path for future scalability to next-generation networks.

The ATCA-7240 is based on two powerful OCTEON II CN68XX processors, each with 32 cnMIPS64 cores and comprehensive hardware acceleration for demanding packet processing, security and deep packet inspection applications with or without I/O.

The ATCA-7240 processing architecture is capable of providing 40 Gbps full duplex line rate processing performance with the OCTEON II 32-core processors. It also features memory capacity of up to a total of 64GB DDR3 on board, enabling a larger number of data flows and subscribers per slot. The ATCA-7240 also supports up to 160 Gigabit Ethernet (GbE) of maximum port density in a single-slot ATCA solution.

Additionally, the ATCA-7240 packet processing module includes a multilayer switch on-board that acts as a Smart Front-End for the OCTEON II processors. This Smart Front-End architecture allows independent resetting of the OCTEON II processing complexes for fault isolation, off-loading and augmenting the OCTEON II data path processing software, and providing flexible data flow options. This inherent versatility provides OEMs the option to re-use the ATCA-7240 across a multitude of different applications.
