Line-Rate Forwarding Performance Switch – Official Technical Overview & Hardware Datasheet

LINE-RATE FORWARDING PERFORMANCE SWITCH

EXECUTIVE SUMMARY

The Line-Rate Forwarding Performance Switch represents a paradigm shift in high-throughput network infrastructure. Engineered for carriers, cloud providers, and large-scale enterprise data centers, this platform delivers deterministic, non-blocking forwarding at wire-speed across all ports and packet sizes. By eliminating head-of-line blocking and ensuring zero packet loss under full line-rate load, the switch guarantees Service Level Agreements (SLAs) for mission-critical applications including high-frequency trading (HFT), AI training clusters, and 5G mobile backhaul. This datasheet provides the complete technical specification, hardware architecture overview, and ordering information for the platform.

ARCHITECTURE & CHASSIS DESIGN

The switch is built around a distributed, shared-memory switching fabric with a line-rate forwarding engine implemented in hardware. Unlike software-dependent or oversubscribed designs, every physical port possesses dedicated bandwidth to the central fabric, ensuring that aggregate throughput scales linearly with port count.

– Non-Blocking Switching Fabric: Total fabric capacity of up to 12.8 Tbps (for the 32x400GbE model) with cell-based switching and virtual output queuing (VoQ) to prevent HOL blocking.
– Hardware Forwarding Engine: Programmable pipeline ASIC supporting L2/L3 forwarding, ACLs, and QoS at line-rate, independent of packet size (64 to 9216 bytes).
– Modular Chassis Options: Available in fixed 1RU (up to 48x25GbE + 8x100GbE), 2RU (up to 32x400GbE), and 4RU modular chassis with up to 8 line card slots.
– Redundancy Architecture: 1+1 hot-swappable power supplies, N+1 redundant fan trays, and optional ISSU (In-Service Software Upgrade) to maintain forwarding during updates.

HARDWARE FEATURES

– Port Configuration: Full-density 1/10/25/40/50/100/200/400GbE front-panel ports (model dependent). All ports support breakout cables (e.g., 1x400GbE to 4x100GbE).
– Forwarding Rate: 100% line-rate, no packet loss for any frame size. Example: 48x25GbE model = 1.2 Tbps switching capacity, 1.2 Bpps (billion packets per second) for 64-byte frames.
– Latency: Sub-microsecond cut-through latency (typically Parameter Specification
