Understanding Remote Direct Data Placement (RDDP) at IETF 56: Enhancing Data Transfer

This document from the 56th IETF meeting on March 18, 1993, outlines Remote Direct Data Placement (RDDP) capabilities with IP transport protocols, particularly SCTP. RDDP facilitates the direct placement of data from the Network Interface Card (NIC) into application buffers, minimizing CPU usage and eliminating costly data copying. It also discusses the performance benefits of RDMA/RDDP in NFS applications and the working group's efforts to establish requirements for NFS and RPC over these transports. Key milestones include draft documents on problem statements and requirements.

  1. Agenda+ beepy IETF IETF 56th – March 18, 1993

  2. What is RDDP? • … enable Remote Direct Data Placement (rddp) capabilities with IP transport protocols, in particular with SCTP. RDDP 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. Remote Direct Memory Access (RDMA) is an example of this concept. IETF 56th – March 18, 1993

  3. RDDP charter addition o RDMA/RDDP enabling The performance benefit of RDMA/RDDP transports in NFS-related applications, by reducing the overhead of data and metadata exchange, has been demonstrated sufficiently such that the working group will pursue in parallel enabling NFS and RPC over the transport defined by the RDDP working group. The WG will restrict its initial activities to defining the problem statement and specifying the requirements for possible extensions to RPC and NFS (in the context of a minor revision). IETF 56th – March 18, 1993

  4. RDDP Milestones APR 03 - Draft problem statement I-D for NFS/RPC/RDDP submitted JUN 03 - Draft requirements document I-D for NFS/RPC/RDDP submitted JUL 03 - AD review of NFS/RPC/RDDP progress and charter IETF 56th – March 18, 1993

  5. Next action: form sub-group • Look for e-mail polling for interested parties to craft problem statement and/or requirements IETF 56th – March 18, 1993
