A Remote Direct Memory Access Protocol Specification
RFC 5040, “A Remote Direct Memory Access Protocol Specification”, is a Proposed Standard document published in October 2007 by R. Recio, B. Metzler, P. Culley, J. Hilland, D. Garcia. It has since been updated by RFC 7146. The canonical text is published by the RFC Editor.
Abstract
This document defines a Remote Direct Memory Access Protocol (RDMAP) that operates over the Direct Data Placement Protocol (DDP protocol). RDMAP provides read and write services directly to applications and enables data to be transferred directly into Upper Layer Protocol (ULP) Buffers without intermediate data copies. It also enables a kernel bypass implementation. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
