1.5 Prerequisites/Preconditions

The protocol functions only in conjunction with the availability of RDMA provider resources on the local machine, including RDMA Network Interface Controller (RNIC) hardware, and a local facility, as described in [RFC4296], to interface with it. These requirements are not discussed in the specification.

The RDMA lower layer provides reliable in-order delivery of sent and received messages, and offers consistency semantics for directly placed data in send/receive message completion, as required by the relevant standards.
