INCREASED BANDWIDTH AND RESILIENCY

Multi-Dimensional Photonic FabricSupport for Intersecting LightRail™ Photonic Interconnects

‒ Increased cross-sectional bandwidth‒ Increased optical paths for bandwidth and

latency engineering

Increased resiliency‒ Redundant control plane paths‒ Additional optical paths for redundancy

and fast local repair

THE PLEXXI-SCALE DATA CENTER

• Multi-Dimensional Optical Fabric‒ Interconnect multiple rings via Switch 2‒ Increase cross-ring bandwidth with additional ring

cross-connects

• Optimize Bandwidth and Latency‒ Global path optimization via Plexxi Control

- Unequal-cost multipath forwarding- Wider traffic distribution than typical SPF-based

forwarding algorithms - Less internal fabric congestion / lower jitter

‒ L1 path engineering via LightRail™ Optical Fabric- maximize bandwidth and/or minimize latency

• Single Point of Control and Integration‒ Centralized interface and API via Plexxi Control
