WebDPDK and RDMA. DPDK leverages VFIO to be able to directly access physical devices in the user space. Note that QEMU/Firecracker also use VFIO to directly assign devices to guest OSes (i.e., device passthrough mode). Although both DPDK and RDMA’s data path bypass kernel, their control path are very different from each other. WebRemote Direct Memory Access (RDMA) is the remote memory management capability that allows server-to-server data movement directly between application memory without any CPU involvement. RDMA over Converged Ethernet (RoCE) is a mechanism to provide this efficient data transfer with very low latencies on lossless Ethernet networks.
