Xelerated's 100 Gbps NPU Aims to Upgrade Carrier Ethernet Market

Xelerated has begun volume production of its HX family of 100G network processors (NPU) for packet-OTN, mobile backhaul/PTN and Carrier Ethernet Switch-Routers. The company said it now racked up 20 system design wins for the HX family of NPUs, the first will go into production later this year. The HX chip delivers wirespeed processing and advanced traffic management with deep packet buffering and can be used for pizza box and line card slot capacities of 20-200 Gbps. These line cards are designed for aggregation and transport, and support a range of interface types including GE, 10GE, 40GE, 100GE and OTU0-OTU4. In mobile backhaul, the HX family implements complete L2 and L3 switch-router applications.

Key features include:

  • Dataflow architecture featuring 448 PISC processor cores and 28 engine access points to connect to on-chip or off-chip table memory and hardware engines

  • Advanced traffic manager with hierarchical per-user, per-service scheduling and shaping and deep off-chip packet buffer fully implemented in DDR3 DRAM

  • Embedded switching with advanced pre-classification for intelligent oversubscription

  • Internet-scale forwarding of IPv4 and IPv6 through high-performance memory interfaces to off-chip TCAM, SRAM and DDR3 DRAM
    Synchronous Ethernet and support for one-step PTP IEEE-1588.

"The high demand for the HX family of NPUs is due to its combination of low power consumption, programmable wirespeed processing and integration of advanced traffic management," said Anders Ericsson, Xelerated VP Sales and Marketing. "We are thrilled about some of our new customer projects now going into production. These platforms have the potential to reshape the Carrier Ethernet market."
