The Architecture of Direct Data Placement and Remote Direct Memory Access on Internet Protocols
RFC 4296, “The Architecture of Direct Data Placement and Remote Direct Memory Access on Internet Protocols”, is an Informational document published in December 2005 by S. Bailey, T. Talpey. The canonical text is published by the RFC Editor.
Abstract
This document defines an abstract architecture for Direct Data Placement (DDP) and Remote Direct Memory Access (RDMA) protocols to run on Internet Protocol-suite transports. This architecture does not necessarily reflect the proper way to implement such protocols, but is, rather, a descriptive tool for defining and understanding the protocols. DDP allows the efficient placement of data into buffers designated by Upper Layer Protocols (e.g., RDMA). RDMA provides the semantics to enable Remote Direct Memory Access between peers in a way consistent with application requirements. This memo provides information for the Internet community.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
