The IESG has approved the following document: - 'RDMA Protocol Extensions' (draft-ietf-storm-rdmap-ext-10.txt) as Proposed Standard This document is the product of the STORage Maintenance Working Group. The IESG contact persons are Martin Stiemerling and Spencer Dawkins. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-storm-rdmap-ext/ Technical Summary This document specifies extensions to the IETF Remote Direct Memory Access Protocol (RDMAP [RFC5040]). 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. The extensions specified in this document provide the following capabilities and/or improvements: Atomic Operations and Immediate Data. Working Group Summary The extensions add Atomic Operations and Immediate Data to the RDMAP Protocol. Other RDMA transport protocols define the functionality added by these extensions leading to differences in RDMA applications and/or Upper Layer Protocols. Removing these differences in the transport protocols simplifies these applications and ULPs. The STORM Working Group chartered this work in mid-2011, and while no significant dissent was encountered, the document spent an extended time in the WG owing to other WG priorities. When work resumed in 2013, the document received substantial attention and review. Four update cycles resulted in the final text. There was no controversy and consensus was easily reached. Document Quality The document is of high quality and is well written. The authors represent companies which deliver industry implementations of the RDDP protocol, and discussion in the STORM WG by developers of upper layers and applications indicated strong interest in using the extensions.
