"A Remote Direct Memory Access Protocol Specification", Renato Recio, 10-Sep-06. (157956 bytes)

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.

"Marker PDU Aligned Framing for TCP Specification", Paul Culley, 9-Oct-06. (169798 bytes)

MPA (Marker Protocol data unit Aligned framing) is designed to work as an "adaptation layer" between TCP and the Direct Data Placement [DDP] protocol, preserving the reliable, in-order delivery of TCP, while adding the preservation of higher-level protocol record boundaries that DDP requires. MPA is fully compliant with applicable TCP RFCs and can be utilized with existing TCP implementations. MPA also supports integrated implementations that combine TCP, MPA and DDP to reduce buffering requirements in the implementation and improve performance at the system level.
