A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : RDMA / TCP
Author(s) : J. Williams
Filename : draft-williams-rdmatcp-00.txt
Pages : 9
Date : 28-Sep-00
This document describes a format for encapsulating RDMA (remote direct
memory access) information within a TCP data stream. No changes or
modification to TCP of any sort are required. This is not intended to
be a protocol, but rather a common format that may be shared by
multiple client protocols, for instance VI/TCP and iSCSI. By using a
common format it is hoped that design of NICs supporting these multiple
protocols can be simplified.
Sufficient information is included in the RDMA message format to allow
determination of the protocol message units, as will as the ability to
process an incoming RDMA request even if previous packets are missing
and awaiting retransmission. In addition a CRC-32 is included in each
segment to enhance the checksum coverage included in TCP.

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.
