NPU Blade for High-Throughput Packet Processing

ADLINK

The aTCA-N700 NPU blade

The aTCA-N700 Advanced Telecommunications Computing Architecture (ATCA) packet processing blade features dual 32-core network processing units (NPUs) for parallel processing and up to 320G switching capability. The blade delivers advanced packet and security processing capabilities for high-performance, high-throughput, low-latency applications in broadband infrastructure elements (e.g., wireless access point controllers, network security platforms, deep packet inspection, IPTV, LTE gateways, and media servers).

The ADLINK aTCA-N700 complies with the ATCA Base Specification (PICMG 3.0 R.3.0) and the ATCA Ethernet Specification (PICMG 3.1 R2.0). It is powered by dual Cavium OCTEON II CN6880 processors, which each have 32 cnMIPS64 V2 cores and a highly optimized architecture for deep packet inspection, network security, and traffic-shaping applications.

Eight memory sockets are provided to support VLP DDR3-1333 REG/ECC up to 128 GB and data transfer bandwidth up to 320 Gbps. The aTCA-N700 blade also supports TCAM for fast router lookup. The blade features a powerful local management processor (LMP) and a quad-core Freescale Semiconductor QorIQ P2041, which makes local management more flexible and convenient and enables the Cavium processors to focus on packet processing.

Each set of NPUs features its own NOR boot flash memory and NAND OS flash memory in a redundant configuration. The LMP has two EEROM for U-Boot image storage and two SSD devices for operating system and application image storage.

For Ethernet connectivity, the aTCA-N700 utilizes the high-performance Broadcom BCM 56842 Ethernet switch to connect the CN6880 packet processors, backplanes, and I/O ports with the switch fabric providing up to 320 Gbps bandwidth. The aTCA-N700 uses dual fabric interface channels and two base interfaces for data transfer.
