BME-3200 - Bandwidth Management Engine

Bandwidth Management Engine

The BME-3200 is the second generation global bandwidth manager element of the Scalable Ethernet Switching product line. The BME-3200 connects to each of the QE-2000s in a system, offering highly reliable N+1 operation. The BME-3200 also enables a highly scalable, non-blocking packet fabric that scales from 20 Gbps to 1.28 Tbps with no performance degradation, regardless of QoS profiles or traffic mix.

The BME-3200 is designed to operate and meet the rigorous requirements of both the Enterprise Core and Metro-Ethernet markets. In tandem with the QE-2000 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.

  • Patented VOQ architecture
  • Administers IP SLAs within the packet fabric
  • Arbitrates up to 32 QE-2000s using a dedicated out-of-band Bandwidth Management Interface to communicate with each QE-2000
  • Dynamically allocates bandwidth to queues to provide bandwidth guarantees
