NPA Network Processor Family

10G NPU with TM for Access Applications

 

EZchip’s NPA 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 aggregation and backhaul. The NPA provides high integration, programmable packet processing and advanced flow-based bandwidth control at 10-Gigabit aggregate throughput.

The NPA integrates several functions normally found in several chips:
  • Programmable packet processing at 10-Gigabit throughput
  • Traffic manager
  • OAM processing offload
  • Synchronous Ethernet and IEEE 1588v2 clock sync offload
  • On-chip memory and external DRAM for lookup tables, statistics and buffering
  • On-chip TCAM for ACLs
  • On-chip Fabric Interface Controller (FIC)
  • Combinations of up to sixteen 1-Gigabit or up to four 10-Gigabit Ethernet MACs, with serial interfaces

Models

Three footprint and software compatible models:
NPA-1: Eight 1-Gigabit Ethernet ports (SGMII/ SERDES)
NPA-2: Sixteen 1-Gigabit Ethernet ports (SGMII/ SERDES)
NPA-3: Configurable to eight 1-Gigabit Ethernet ports (SGMII/SERDES) and two 10-Gigabit Ethernet ports (XAUI); or twelve 1GE and one 10GE ports; or four 10GE ports
SGMII interfaces support 2.5Gbps SERDES for GPON applications

Target Applications

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

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

System Configurations

NPA’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.
