Remote Direct Memory Access over IP Problem Statement
RFC 4297, “Remote Direct Memory Access over IP Problem Statement”, is an Informational document published in December 2005 by A. Romanow, J. Mogul, T. Talpey, S. Bailey. The canonical text is published by the RFC Editor.
Abstract
Overhead due to the movement of user data in the end-system network I/O processing path at high speeds is significant, and has limited the use of Internet protocols in interconnection networks, and the Internet itself -- especially where high bandwidth, low latency, and/or low overhead are required by the hosted application.
This document examines this overhead, and addresses an architectural, IP-based "copy avoidance" solution for its elimination, by enabling Remote Direct Memory Access (RDMA). 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.
