QE-2000 - Queuing Engine

Queuing Engine

The QE-2000 is the second generation queuing and fabric interface device of the Scalable Ethernet Switching product line. It performs as a 20 Gbps full-duplex queuing engine with external packet buffer memory. The QE-2000 has two SPI-4.2 interfaces for connectivity to packet processing devices.

The QE-2000 is designed to operate and meet the rigorous requirements of both the Enterprise Core and Metro-Ethernet markets. In tandem with the BME-3200 and SE-4000 it forms part of the switch fabric which delivers bandwidth guarantees, advanced traffic engineering, and per-flow queuing across its extremely low-latency and highly-resilient fabric.

  • 20 Gbps full-duplex traffic manager
  • Manages up to 16K queues
  • Supports up to 16 Classes of Service (CoS)
  • Deep ingress buffers for Round Trip Time (RTT) and QoS -using up to 512 MB of external commodity DRAMs
