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 document is a product of the Remote Direct Data Placement Working
Group of the IETF.
