Multimedia Mail Meeting Notes
Status of this Memo
This memo is a report on a meeting about the experimental multimedia
mail system (and in a sense a status report on that experiment).
Distribution of this memo is unlimited.
A meeting was held at Bolt Beranek and Newman on 23-24 July 1984 to
discuss recent progress by groups who are building multimedia mail
systems and to discuss a variety of issues related to the further
development of multimedia systems. Representatives were present from
BBN, ISI, SRI and Linkabit. The list of attendees appears at the end
of this note.
The result of this meeting is a series of agreements that will be
incorporated in the next set of experiments with multimedia mail as
well as a set of items for further action.
Note: There are references in this document to notes in a series
devoted to multimedia mail. These notes are available on-line in the
directory [USC-ISIF]<MMM> and have the names MMM-N.TXT where N is the
note number. The file MMM-INDEX.TXT is a list of all of the notes in
the series. These public files may be copied via FTP using the FTP
username ANONYMOUS and password GUEST.
2. Review of Status
Status reports on work accomplished in the last year were given by
The initial implementation of Diamond is complete and runs on the
Jericho workstation. Diamond currently supports the exchange of
compound documents which contain text, graphics, images, voice and
spreadsheet/charts. A demonstration of this system was presented
showing both the user's view of Diamond messages and message
management as well as the interactions between the components of this
distributed system. Diamond currently uses the TOPS-20 implementation
of MPM for inter-cluster message transport but the plan is to
integrate an implementation of MPM for the Sun Workstation into
Diamond. Current activity is focused on porting Diamond to the Sun
Workstation. A first version of Diamond for the Sun is nearly

completed and parts (the document editor) were demonstrated running
on the Sun. Diamond will be used in the ADDCOMPE testbed with
100-200 users expected in the next year or so. Future plans include
building on the experience gained with Diamond in the area of
multimedia conferencing, extending the use of multimedia into other
application areas and applying the distributed architecture of
Diamond to other application areas.
A new effort aimed at developing a user interface on a Xerox 1108
(Dandelion) workstation has just begun. All of the implementation is
being done in Interlisp. Initial work has been done to implement IP
and TFTP on the 1108 as well as a document editor that makes use of
the Interlisp-D window system. Work on the user interface that was
developed on the Perq will be cycling down. The implementation of
the MPM on TOPS-20 is essentially complete with the addition of MPM
to SMTP mail conversion; no major changes are anticipated. The
TOPS-20 MPM will be used as the message transport facility for the
1108 user interface implementation. TFTP will be used to get
messages from the 1108 to the TOPS-20.
The SRI multimedia mail system consists of three parts: The
Multimedia Mail Handler (MMH) which is the user's interface for
managing mail, the Structure Editor (SE) which is used to view and
compose multimedia messages and the MPM for mail transport. This
system is implemented on the Sun Workstation. The first release of
the MPM on the Sun will be ready for distribution at the end of this
summer. The SE is used to view and compose structures of multimedia
objects. Currently there is support for text, voice and graphics.
Another effort at SRI involves integration of applications to run in
the ADDCOMPE testbed. Diamond will be the first example of an
application which uses multimedia data in the testbed. SRI is
interested in examining the issues associated with multimedia systems
to determine how multimedia data can be used in other applications
that might be put into the testbed.
Linkabit has recently received a contract to work on protocol
evaluation, problems associated with working in a large internet
environment, and new real-time end-to-end services. They will be
working with Sun workstations. Areas of interest are protocols,
multimedia conferencing and domains.
