NP-4 Network Processor

100-Gigabit NPU with Integrated TM & CPUs


EZchip's NP-4 is a highly-flexible network processor with integrated traffic management targeting Carrier Ethernet Switches and Routers (CESR) and other Carrier Ethernet platforms that require high performance, flexible packet processing and fine-grained traffic management.

NP-4 highlights include:
  • 100 Gbps throughput for building 40-400 Gigabit line-cards and pizza boxes
  • Integrated traffic management providing granular bandwidth control
  • Enhanced support for video streams and IPTV
  • On-chip control CPU for host CPU offload
  • Power management for minimizing line card and system power dissipation
  • Operations, Administration and Management (OAM) processing offload
  • Synchronous Ethernet and IEEE1588v2 offload for Circuit Emulation Services
  • IP reassembly for advanced packet processing offload
  • Integrated serial ports with support for 1, 10, 40 and 100 Gigabit Ethernet
  • Single 40G MAC
  • On-chip Fabric Interface Controller for interfacing to Ethernet-based as well as proprietary switch-fabric solutions
  • Utilizing DDR3 DRAM memory chips for minimizing power and cost
  • Software compatible with EZchipís NP-2, NP-3 and NPA network processors


The NP-4 is available in two models for diverse configurations and price points:
  • NP-4 provides 100-Gigabit throughput.
  • NP-4L (Light) provides 50-Gigabit throughput.
  • Both devices have same package, pin out, interfaces and are s/w compatible


NP-4ís flexibility and integration allows system vendors to deliver cost effective solutions that can easily adapt to changing market requirements. Typical applications include:


Line cards in modular chassis: Stand-alone pizza box solutions:
  • Metro Switches
  • Edge and Core Routers
  • Wireless Backhaul Aggregation Switch/Routers
  • Enterprise Backbone Switches
  • Ethernet Aggregation Nodes
  • EPON/GPON OLTs and cable CMTS
  • Firewalls, VPN and Intrusion Detection Appliances
  • Server Load Balancing Switches
  • Network Monitoring and Analysis Services
