RoCE
RDMA over Converged Ethernet, a network protocol that enables RDMA functionality over standard Ethernet infrastructure. It is widely deployed in AI data centers and high-performance computing clusters for high-speed network interconnection.

RoCE和InfiniBand是常见的RDMA实现。
AMD's ROCm ecosystem achieves RDMA capability by supporting RDMA over Converged Ethernet (RoCE), competing with InfiniBand-based solutions.
GPUs transmit gradient data via InfiniBand or RoCE protocols, with bandwidth reaching 400 Gbps per card or higher.
The Intel E810 network card supports RoCE v2, enabling multiple machines to exchange data with lower latency and higher bandwidth via RDMA over Converged Ethernet, for building inference clusters.
RoCE is an implementation of RDMA over standard Ethernet, with lower deployment costs compared to traditional RDMA deployments that require dedicated InfiniBand networks.
In traditional networking solutions, network jitter and protocol overhead typically result in actual bandwidth utilization of only 60%–70%
High-speed networks such as InfiniBand or RoCE directly access remote node memory via RDMA technology, bypassing the security mechanisms of the traditional TCP/IP protocol stack.
