A Remote Direct Memory Access Protocol Specification

Remote Direct Memory Access Transport for Remote Procedure Call

“…These terms, common in the RDMA lexicon, are used in this document. A more complete glossary of RDMA terms can be found in [RFC5040].…”

“…This protocol conveys to the RPC peer information sufficient for that RPC peer to direct an RDMA layer to perform transfers containing RPC data and to communicate their result(s). For example, it is readily carried over RDMA transports such as Internet Wide Area RDMA Protocol (iWARP) [RFC5040,RFC5041], or InfiniBand [IB].…”

“…Remote Direct Memory Access (RDMA) [RFC5040,RFC5041], [IB] is a technique for efficient movement of data between end nodes, which becomes increasingly compelling over high-speed transports. By directing data into destination buffers as it is sent on a network, and placing it via direct memory access by hardware, the double benefit of faster transfers and reduced host overhead is obtained.…”

Securing Block Storage Protocols over IP: RFC 3723 Requirements Update for IPsec v3

“…Introduction [RFC3723] specifies IPsec requirements for block storage protocols over IP (e.g., iSCSI [RFC3720]) based on IPsec v2 ( [RFC2401] and related RFCs); those requirements have subsequently been applied to remote direct data placement protocols, e.g., RDMAP [RFC5040]. This document updates RFC 3723's IPsec requirements to IPsec v3 ( [RFC4301] and related RFCs) to reflect developments since RFC 3723 was published.…”

Applicability of Remote Direct Memory Access Protocol (RDMA) and Direct Data Placement (DDP)

“…Remote Direct Memory Access Protocol (RDMAP) [RFC5040] and Direct Data Placement (DDP) [RFC5041] work together to provide applicationindependent efficient placement of application payload directly into buffers specified by the Upper Layer Protocol (ULP).…”
