Re: [storm] I-D Action: draft-ietf-storm-iser-03.txt

Mike,

Thanks for submitting this updated draft.

In Section 14 (Appendix A), please add a discussion of backwards compatibility with RFC 5046 - it's important to explain how an implementation based on this draft will interact with a hypothetical implementation based on RFC 5046.  As part of this, it's important to identify changes that are incompatible with RFC 5046, but compatible with existing implementations because the implementations did something different from RFC 5046.  As a start, it would help to identify each numbered change as backwards-compatible (with RFC 5046) vs. backwards-incompatible (because RFC 5046 got it wrong in 20/20 hindsight).

Thanks,
--David

The summary of changes since RFC 5046 can be found in section 14.  In particular, the following changes were made since the -02 version of the draft:

8. Added two 64-bit fields in iSER header in section 9.2 for the Read Base Offset and the Write Base Offset to accommodate a non-zero Base Offset.  This allows one implementation such as the OFED stack to be used in both the Infiniband and the iWARP environment.  Changes were made in the definition of Base Offset, Advertisement, and Tagged Buffer.  Changes were also made in sections 2.4.1, 2.5, 2.6, 7.3.1, 7.3.3, 7.3.5, 7.3.6, 9.1, 9.3, 9.4, 9.5.1, and 9.5.2.
9. Remove iWARP specific behavior.  Changes were made in the definition section on RDMA Operation and Send Message Type.  Changes affecting Send with Invalidate were made in sections 2.4.1, 2.5, 2.6, 4.1, and 7.3.2.  Changes affecting Terminate were made in sections 10.1.2.1 and 10.1.2.2.  (Forgot to mention here that section 15 was also updated to remove iWARP specific behavior.)
10. Denial of service descriptions for the initiator in section 5.1.1 was removed since it is applicable for the target only.

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the STORage Maintenance Working Group of the IETF.

Title           : iSCSI Extensions for RDMA Specification
Author(s)       : Michael Ko
                          Alexander Nezhinsky

   iSCSI Extensions for RDMA provides the RDMA data transfer capability
   to iSCSI by layering iSCSI on top of an RDMA-Capable Protocol.  An
   RDMA-Capable Protocol provides RDMA Read and Write services, which
   enable data to be transferred directly into SCSI I/O Buffers without
   intermediate data copies.  This document describes the extensions to
   the iSCSI protocol to support RDMA services as provided by an RDMA-
   Capable Protocol.

   This document obsoletes RFC5046
