400G AI RoCE Data Center Network Solution

SwitchInfra 400G RoCE lossless network solution offers a full-stack, integrated approach spanning from network hardware to management software. RoCE uses standard Ethernet to deliver high-performance RDMA with low operational cost. Powered by 400G PicOS® Ethernet switches and the AmpCon-DC Management Platform, the solution utilizes intelligent congestion control (DCQCN, PFC, ECN) to achieve automated deployment and lossless networking for AI training and inference workloads. The spine-leaf fabric architecture maximizes GPU utilization while reducing job completion times.

Full-Stack Integration

From PicOS® switches to AmpCon-DC management and optical interconnects, SwitchInfra provides a vertically integrated solution. End-to-end validation ensures all components work together seamlessly for AI workloads.

Standard Ethernet Economics

RoCEv2 runs on standard Ethernet switches, eliminating the cost and complexity of proprietary interconnects. IT teams use familiar tools and workflows, reducing training overhead and operational expenses.

Automated Operations

AmpCon-DC enables zero-touch provisioning and automated fabric deployment. Real-time telemetry and congestion analytics provide proactive insights for network operations teams.

Technical Capabilities

DCQCN Congestion Control

Data Center Quantized Congestion Notification combines ECN marking with rate-based flow control. Switches detect incipient congestion and signal senders to reduce injection rates before queues overflow.

Priority Flow Control

IEEE 802.1Qbb PFC creates lossless Ethernet classes for RoCEv2 traffic. Per-priority pause prevents packet loss during microbursts while allowing best-effort traffic to continue unaffected.

Dynamic Load Balancing

Hardware-based DLB distributes flows across all ECMP paths based on real-time link utilization rather than static hashing. Prevents polarization and maximizes bisectional bandwidth utilization.

Telemetry & Visibility

In-band Network Telemetry (INT) and streaming telemetry provide microsecond-granularity visibility into PFC pauses, ECN marks, and buffer occupancy. AmpCon-DC dashboards surface congestion hotspots in real time.
