Unlock Seamless AI & HPC Connectivity with Link Layer Retry (LLR)
As AI and High-Performance Computing (HPC) dominate the landscape of data centers, the need for robust solutions to combat packet loss and latency becomes critical. Traditional Ethernet struggles here, but the Ultra Ethernet Consortium’s Link Layer Retry (LLR) offers a game-changing approach.
Why LLR Matters:
- Local Loss Recovery: Detects and retries packet loss at the link layer, ensuring low latency.
- Streamlined Process: Avoids complex vendor-specific solutions like RDMA.
- Enhanced Throughput: Maintains synchronization across computations without overwhelming the CPU.
Key Features of LLR:
- Frame transmission with sequence numbering ensures organized data flow.
- Buffered retries allow real-time corrections without disrupting higher layers.
- Acknowledgment mechanics confirm successful communications swiftly.
