A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : RNIC Interoperability
Author(s) : J. Carrier, J. Pinkerton
Filename : draft-carrier-rddp-rnic-interop-00.txt
Pages : 18
Date : 2004-11-22
This document describes a mechanism for enabling RDMA Network
Interface Cards (RNICs) that implement both the IETF and RDMAC
versions of the DDP and RDMAP protocols to interoperate with legacy
RNICs that are based on the RDMAC version of the protocols. The
proposed scheme uses MPA Request/Reply Frames to negotiate the
protocol version as well as MPA marker and MPA CRC. A ULP or other
supporting entity must perform this negotiation on behalf of the
RDMAC RNIC because RDMAC MPA does not define an MPA connection
scheme using MPA Request/Reply frames. This draft also makes
specific recommendations for minor changes to the IETF MPA, DDP, and
RDMAP internet drafts to aid in interoperability.

In the body type:

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
