I've placed the following project proposal on the SCSI Working Group agenda
for Wednesday afternoon.  Keith Parker (the author) plans to be there.  I
expect that if the working group concurs, there will be a forwarding motion
on Thursday at the T10 meeting.  Please read the project proposal and send
any substantive comments to the reflector.  Please send any purely
editorial comments to me.

Thanks,

John Lohmeyer

                               Project Proposal
                                   For a New
                                  X3 Standard


                           SCSI Socket/SSL Services
                                     (SSS)
                                  Command Set


                               February 24, 1997

1.    IDENTIFICATION OF PROPOSED PROJECT
1.1   TITLE:  SCSI Socket/SSL Services (SSS) Command Set
1.2   PROPOSER:  X3T10.
1.3   DATE SUBMITTED:  February 24, 1997
1.4   PROJECT TYPE: D - Development of a standard within an X3 TC.

2.    JUSTIFICATION OF PROPOSED STANDARD
2.1   NEEDS:

The SCSI standard currently does not include a command set to implement a
Platform/Device Independent (PDI) SCSI Socket/SSL Services (SSS) interface at
the Application Programming Interface (API) level.

When communication devices are accessed at the hardware register level it is
impossible to have a secure system due to the problems of cipher key
management and promiscuous software.

When communication devices are accessed at the hardware register level
portability between platforms is severely limited/complicated by the large
quantity of platform/device specific systems software required between the
register level hardware and the platform/device independent Socket/SSL
Applications Programming Interface (API).

Despite user interest in processor to processor communication via SCSI, there
is currently no comprehensive SCSI command set for implementing processor to
processor communication via SCSI.

There is no SCSI command set that allows standard socket applications such as
e-mail or web browsers to platform/device independently access SCSI devices.
The SCSI Socket/SSL Services (SSS) command set would allow all
hard/firm/software to implement a rational and SECURE Socket/SSL system to be
physically inside a communication device.  The SSS could also be used for
direct processor to processor communication via SCSI.

The SCSI Socket/SSL Services (SSS) command set would allow any real/virtual
device to implement any useful Internet Request for Comment (RFC) to provide
services such as HTTP, FTP, PING, FINGER, SMTP, POP3, DHCP, TELENET, & others
platform/device independently.

2.2   RECOMMENDED SCOPE OF STANDARD:

The SSS standard will define a platform and device independent method of
communication between processor devices and communication devices or other
processor devices.

The SSS standard will be optimized for platform/device independence.

The SSS standard will provide "hooks" to allow SSS compatible devices to be
dynamically integrated into a future platform/device independent File System
SCSI command set.

2.3   EXISTING PRACTICE IN AREA OF PROPOSED STANDARD:

The proposed project involves consolidation and evolutionary expansion of the
present SCSI standards.

2.4   EXPECTED STABILITY OF PROPOSED STANDARD WITH RESPECT TO CURRENT AND
   POTENTIAL TECHNOLOGICAL ADVANCE:
   
The nature of the proposed project is to insure that SCSI has an upward,
highly compatible growth path.  This will insure that current investments in
SCSI are provided with more stability in the face of technological
developments.

3.    DESCRIPTION OF PROPOSED PROJECT:
3.1   TYPE OF DOCUMENT:  Standard.
3.2   DEFINITION OF CONCEPTS AND SPECIAL TERMS:  None.
3.3   EXPECTED RELATIONSHIP WITH APPROVED X3 REFERENCE MODELS:

The SSS standard is intended for use in closed systems.

3.4   RECOMMENDED PROGRAM OF WORK:
The following program of work is planned for the SSS:
   (1)   Solicit continuing participation by the current membership of X3T10
         through X3 procedures.  Invite comments and proposals from
         organizations that may have a contribution to the SSS standard.
   (2)   Prepare a draft proposed standard based on proposals submitted and
         other information gathered during the initial investigation.
   (3)   Consider the results of SSS testing as may be available to the
         committee through the voluntary efforts of the X3T10 membership.
   (4)   Submit the draft proposed standard to X3 for further processing.
   
3.5   RESOURCES - INDIVIDUALS AND ORGANIZATIONS COMPETENT IN THE SUBJECT
   MATTER:
The current membership of X3T10 includes representatives from all parts of the
computer industry, from semiconductor chip manufacturers to large mainframe
system manufacturers as well as government agencies.  The members of X3T10
have expressed their desire to participate and cooperate in the development of
this proposed standard.

There are sufficient resources to complete the development of this standard
without delaying work on other projects.

3.6   RECOMMENDED X3 DEVELOPMENT TECHNICAL COMMITTEE:
It is recommended that the development work be done in Technical Committee
X3T10 which is responsible for developing the family of SCSI standards.

3.7   ANTICIPATED FREQUENCY AND DURATION OF MEETINGS:
Technical Committee X3T10 meets bimonthly. Specific task ad hoc groups are
called as may be required for one to three days between the regular meetings
but their results are not binding.

3.8   TARGET DATE FOR dpANS TO X3:  July 1998.
3.9   ESTIMATED USEFUL LIFE OF STANDARD:
It is anticipated that this standard will have a life of 5 years.

4.    IMPLEMENTATION IMPACTS
4.1   IMPACT ON EXISTING USER PRACTICES AND INVESTMENTS:
The proposed SSS standard will provide an evolutionary growth path to the
existing practices and investments.  It is likely that any isolated negative
impacts would occur in any case through non-standard evolution or revolution.

4.2   IMPACT ON SUPPLIER PRODUCTS AND SUPPORT:
The proposed SSS standard will provide an evolutionary growth path to the
existing practices and investments.  It is likely that any isolated negative
impacts would occur in any case through non-standard evolution or revolution.

4.3   TECHNIQUES AND COSTS FOR COMPLIANCE VERIFICATION:
The committee will consider the results of SSS testing as may be available to
the committee through the voluntary efforts of the various participants in
X3T10.  With this method all costs are borne by the organizations of the
various participants and have for the most part been mainly an adjunct of
their normal development costs.

4.4   LEGAL CONSIDERATIONS:
There are no known legal considerations.  A Call for Patents will be made.
