The tools have been selected to provide a baseline set for multimedia conferencing. The baseline we have chosen is that the tools should be RTP/2 compliant.

The following tools are delivered:

Audio: VAT 4.0

Video: VIC 2.7

Shared workspace: WB 1.59

NTE 1.6

Conference control: SD 1.16

We have documented each of the tools under the headings Release Description, Systems Requirements List, Installation Guidelines, and the Web source for the software.

This is an Internal deliverable which we have chosen to document and make available. All the tools described in this document are freely available on World-Wide Web and ftp sites around the world. We have documented each of the tools under the headings Release Description, Systems Requirements List, Installation Guidelines, and the Web source for the software.

SDR, FreePhone and Rendez-Vous are new tools made available since our Initial software deliverable (D0).

The other tools - RAT, VAT and VIC are released as versions with in-built encryption which has been added by the MERCI project so that, in the case of the tools developed in the USA, they are not covered by US export restrictions on the export of cryptography.

This is a Project deliverable. For various reasons, which we elaborate on in this document, we will delay delivery of some tools and provide improved versions of some of the others after our demonstration at JENC8.

The tools we are delivering are freely available on World-Wide Web and ftp sites around the world. We have documented each of them under the headings Release Description, Systems Requirements List, Installation Guidelines, and the Web source for the software. Although we provided versions of the released tools in February, we have updated this deliverable following JENC8 at which we demonstrated further improvements.

FreePhone, Rendez-Vous and RAT, delivered in D1, are now given added functionality and are available on more platforms. FreePhone now provides high-frequency sampling and supports stereo and the L16 codec. Rendez-Vous is now compatible with VIC and available for PCs running FreeBSD and Windows 95/NT. RAT provides mixing functionality to allow use in a gateway and16 bit encoding on all codecs.

The Secure Conferencing User Agent (SCUA) from GMD is included below.

Network Monitor, developed by CRC was originally submitted, but, with the further development of this prototype into the MultiMON tool, which was released in July, we now submit this in its place.

This is a Project deliverable. The tools we are delivering are freely available on World-Wide Web and ftp sites around the world. We have documented each of them under the headings Release Description, Systems Requirements List, Installation Guidelines, and the Web source for the software.

In this deliverable we offer:

• UTG – the UCL Transcoding Gateway

This tool allows a user to use a client program on a PC to link to an Mbone conference via IP/ISDN or any unicast link. The client makes a unicast connection to a server which is on a multicast capable network.

• TELES H.320 to Mbone gateway

This is the precursor of a tool to allow interworking between multiple participants in an H.320 conference and Mbone conference participants. This first release allows a single H.320 terminal to join an Mbone conference.

• MMCR – the Multicast Multimedia Conference Recorder

MMCR is a client and a server which allows the user to record, playback and perform simple VCR-like tasks on multicast conference streams which may be encrypted or not.

Title of Deliverable: Security Architecture for MERCI

Work-Package contributing to the Deliverable: 10

Nature of the Deliverable: (PR/RE/SP/TO/OT)^** SP

Author(s): Knut Bahr, Stefan Braun, Elfriede Hinsch, Peter Kirstein

Abstract:

This deliverable provides the security architecture to be used in MERCI project - to the extent that it has been defined. We first overview the facilities provided in a number of other projects, in particular the following: PASSWORD, ICE-TEL, Van Jacobson's MBONE, MICE, the IETF and ITU-T. These facilities in some of the earlier work like PASSWORD and the MICE work have been superseded; only a specific subset of ICE-TEL's are applicable; Van Jacobson's work is not well documented; the IETF and the ITU-T activities are not fully compatible, and in many cases the relevant standards still being defined. Next we give an overview of the MBONE tools and protocols, in their unsecured state; this serves as a basis for the later work. We then overview general security considerations, and analyse security implementations as they are relevant to conferencing. An overview is provided of the ITU-T protocols relevant to conferencing; many of these need to be extended for secure conferencing.

Having provided the necessary background, two chapters provide the meat of this Deliverable. First we specify the security procedures to be used for MBONE conferencing. These include both securing the basic tools, and providing mechanisms for key distribution. Here our main proposal is to use modified versions of the Session Announcement and Session Description protocols; these are reliant on Public Key systems, and methods for key distribution by Directory, WWW and electronic mail procedures. Finally, we go through a similar exercise for the securing of coupled ITU-T and MBONE conferences; here the ITU-T mechanisms are not fully defined, and different facilities for securing the coupled systems are needed.

Deliverable Number: D11.1

Contractual Date of Delivery: 31. August 1996

Title of Deliverable: Seminar Deliverable I

Work-Package contributing to the Deliverable: 11

Author(s): Peter Feil, University of Stuttgart

Andreas Rozek, University of Stuttgart

Abstract:

Based on the results of the earlier MICE project, MERCI - Multimedia European Research Conferencing Integration - aims to integrate technology components to allow for proper development of tools for multimedia collaboration.

The components developed within MERCI technology workpackages are tested within validation workpackages and the feedback is used to improve theses tools further. Once they are considered rugged enough they are made available to other projects and institutions.

As distance education is an excellent consumer of the MERCI technology, the "Seminar Workpackage" (WP11) has been organised to apply the tools in several distributed seminars.

This deliverable describes the work that has been done within the Seminar Workpackage in the reporting period. It covers the regular networked multimedia project meetings and the first set of MERCI seminars. A short introduction into booking systems for MBone events is also given.

Title of Deliverable: Seminar Deliverable IV

Work-Package contributing to the Deliverable: 11

Author(s): Andreas Rozek, University of Stuttgart

Abstract:

Based on the results of the earlier MICE project, MERCI - Multimedia European Research Conferencing Integration - aims to integrate technology components to allow for proper development of tools for multimedia collaboration.

Every tool developed within the project is tested by a validation workpackage - the feedback is then used to improve that tool. All tests are performed under the \004real" conditions of a given application scenario - one of them being \004distance education" handled by MERCI WP11, the " Seminar Workpackage" (WP11).

As a \004demonstrator", this deliverable consists of a seminar recording on disk and this accompanying paper which additionally shows some screen snapshots and describes the experiences gained from these seminars.
