I would like to have a voulonteer which can be a technical advisor from Applications Area for this wg. Anyone having interest, please let me and Ned know. paf ---------- Forwarded Message ---------- Date: måndag 17 juni 2002 09.35 -0400 From: Steve Coya <scoya@cnri.reston.va.us> To: IETF-Announce Subject: WG Review: Remote Direct Data Placement (rddp) A new IETF working group has been proposed in the Transport Area. The IESG has not made any determination as yet. The following Description was submitted, and is provided for informational purposes only: Remote Direct Data Placement (rddp) ----------------------------------- Current Status: Proposed Working Group Description of Working Group: The purpose of this WG is to enable RDMA Remote Direct Memory Access capabilities with IP transport protocols, in particular with SCTP. RDMA capabilities refer to the ability to place data directly from the NIC into application buffers, without intensive CPU usage. This strategy avoids the costs of data copying and enables using IP as a method for high speed buffer to buffer transfer, allowing IP to replace special purpose networks currently in use. Conceptually, RDMA functionality can be viewed as consisting of two layers. First the direct data placement capability, which is accomplished through a tag and a lookup table on the NIC. Above this core functionality, an RDMA control protocol is needed to specify how the direct data placement can be used, for example READ and WRITE commands. The work of the WG is to accomplish three items: 1) A (transport independent) protocol core to support direct data placement from the NIC into specified memory, usually application buffers. 2) A (transport independent) protocol core layered on top of the direct data placement protocol that specifies control of RDMA. 3) A mapping of the direct data placement protocol and the RDMA control protocol to SCTP. ---------- End Forwarded Message ----------
