Subject: [nfsv4] Resend: NFS / RPC / RDMA drafts available

From: "Talpey, Thomas" <[email-masked]>

Three new drafts are available in the I-D directory today:
        (http://www.ietf.org/ids.by.wg/none.html)

We look forward to discussing these on the list, and at the
interim working group meeting next month!

Apparently the URLs are slightly scrambled for two of the documents,
the first draft appears under the second's title! We'll look to clean this
up, obviously... The correctly associated URLs appear below, fixed
from my first mail. Sorry for the glitch.

"RDMA Transport for ONC RPC", Thomas Talpey, Brent Callaghan, 15-May-03. (11729 bytes)  
<http://www.ietf.org/internet-drafts/draft-callaghan-rpcrdma-00.txt> 
A protocol is described providing RDMA as a new transport for ONC RPC. The RDMA transport binding conveys the benefits of efficient, bulk data transport over high speed networks, while providing for minimal change to RPC applications and with no required revision of the application RPC protocol, or the RPC protocol itself. 

"NFS Direct Data Placement", Thomas Talpey, Brent Callaghan, 15-May-03. ( bytes)  
<http://www.ietf.org/internet-drafts/draft-callaghan-rpc-rdma-00.txt> 
The RDMA transport for ONC RPC supports direct data placement for NFS data. Direct data placement not only reduces the amount of data that needs to be copied in an NFS call, but allows much of the data movement over the network to be implemented in RDMA hardware. This draft describes the use of direct data placement by means of server- initiated RDMA Writes into client-supplied buffers in a Write list for implementations of NFS versions 2, 3, and 4 over an RDMA transport. 

"NFSv4 RDMA and Session Extensions", Thomas Talpey, Spencer Shepler, 15-May-03. (111000 bytes)  
<http://www.ietf.org/internet-drafts/draft-talpey-nfsv4-rdma-sess-00.txt> 
Extensions are proposed to NFS version 4 which enable it to support sessions, connection management, and operation atop RDMA-capable RPC. These extensions enable universal support for Exactly-once Semantics by NFSv4 servers, enhanced security, and multipathing and trunking of transport connections. These extensions provide identical benefit over both TCP and RDMA connection types.
