RDMA over Converged Ethernet
is a feature of the Network Interface Card (NIC) that allows one computer to have direct memory access to another one bypassing the kernel. RDMA
over Converged Ethernet (RoCE
) brings the low-latency and efficiency benefits of InfiniBand
to the data center Ethernet fabric. RoCE
(pronounced "Rocky") is a link layer protocol that allows communication between two hosts in the same domain and that provides efficient data transfer with very low latencies on lossless Ethernet networks.
