18 * RDMA Migration Protocol Description
28 RDMA helps make your migration more deterministic under heavy load because
30 because the RDMA I/O architecture reduces the number of interrupts and
31 data copies by bypassing the host networking stack. In particular, a TCP-based
32 migration, under certain types of memory-bound workloads, may take a more
