| ⚡ RDMA over Converged Ethernet (RoCE) High-Performance RDMA Transport Across Ethernet Networks | |
| RDMA over Converged Ethernet (RoCE) extends Remote Direct Memory Access (RDMA) across Ethernet networks, enabling direct memory-to-memory communication with ultra-low latency and minimal CPU overhead. RoCE has become a foundational transport for AI training clusters, hyperscale cloud infrastructure, high-performance computing, and modern storage networks. | |
| Why It Matters | Modern GPU clusters require fast, predictable communication between thousands of accelerators. RoCE combines the efficiency of RDMA with the scalability and economics of Ethernet, making it a widely deployed transport for distributed AI, cloud computing and high-performance storage. |
