NPA-0 Network Processor

5G NPU with integrated TM and CPU for Access Applications

 

EZchip’s NPA-0 is a highly-flexible network processor with integrated traffic management targeting Ethernet network access platforms (ONT/OLT GPON/EPON), copper access platforms (DSLAM) and demarcation devices, and 3G/4G WiMAX base stations for aggregation and backhaul. The NPA-0 provides high integration, programmable packet processing and advanced flow-based bandwidth control at 5-Gigabit aggregate throughput.

 

> For additional details refer to NPA-0 Product Brief.

 

The NPA-0 integrates several functions normally found in several chips:
  • Programmable packet processing at 5-Gigabit throughput
  • Traffic manager
  • Classification search engines
  • On-chip control CPU 650 MIPS
  • OAM processing offload
  • Synchronous Ethernet and IEEE 1588v2 clock sync including boundary clock support
  • On-chip memory for lookup tables and statistics
  • On-chip TCAM for ACLs
  • On-chip Ethernet Fabric Interface Controller (FIC)
  • Eight 1-Gigabit and twelve Fast Ethernet MACs

Target Applications

Programming delivers a variety of applications such as L2 switching, Q-in-Q, MAC-in-MAC, PBB-TE, PBT, T-MPLS, MPLS-TP, VPLS, MPLS and IPv4/IPv6 routing.

Line card, service card and pizza box applications:
  • Fiber and copper Ethernet access switches
  • Ethernet demarcation devices
  • Wireless backhaul and base station aggregation (3G/4G and WiMax)
  • Copper access (DSLAMs)
  • Optical access (GPON/EPON OLTs and ONUs)

 

System Configurations

NPA-0's flexibility and integration allows system vendors to deliver cost effective solutions that can easily adapt to changing market requirements. Illustrated below are several sample solutions.
