80G Packetarium™ – “ATCA rewrapped”Shrink & Cost-down for non-HA DPI Packetarium is a cost-optimized, modular system architecture for multicore packet processing. Scalable and upgradable to meet bandwidth demand, it’s also a cost effective alternative to 1, 2 or 4 x 10GbE (XAUI) per board ATCA. 8 boards per system Trade-off on availability (system level) QorIQ up to 128 cores MIPS64 up to 256 cores The all-IP design simplifies customization and TI DSP up to 480 cores X86 in design the identical system management design preserves ATCA S/W investment. The Mainboard’s topology is similar to ATCA backplane + switch with transition modules + chassis management modules Each network processing board connects to mainboard’s switch via 2 or 4 x 10GE (XAUI)

Accurate user packet identification and QoS classification. Efficient packet steering decisions for optimized application-level processing Advanced content inspection functions Application-aware firewall, video compression.
Introducing the 6WIND Solution High-performance packet processing engine. DPI Application Processing Optimized for DPI acceleration and protocol termination. Linux Includes comprehensive set of networking protocols with High ……. Availability support. Fast path architecture maximizes Multicore Processor system throughput. Advantech Platform Used by tier-1 OEMs worldwide.
Packet Detection Challenges Wire-speed performance. Packets may be fragmented and need re-construction. Packet always hidden by combination of encapsulation techniques VLAN, GTP, IP in IP, GRE, L2TP, MPLS… Packet is often encrypted (IPsec). Integrated firewall required. Latency for each packet has to be minimized. Solution requires high-performance packet processing for packet identification, classification, steering and termination.
