2.1 Transport

The following sections specify how messages are represented on the wire and specify the protocol data types.

The protocol operates over an RDMA transport which MUST support reliable in-order message delivery, and MUST support remote direct data placement via RDMA Write and RDMA Read requests. Examples of such transports are iWARP, Infiniband and RoCE, as described in section 1.4. A local interface supporting the Verbs semantic is typically provided by the local operating system, specified in [DRAFT-RDMA-VERBS] and [IBARCH].
