-------- the message i sent about multimedia for europe was a bit premature - sorry, enthusiasm got the better of me. the project is not yet funded... you will certainly know as soon as we find out! note, also, that the protocol stack is subject to much study (as one would expect for continous media, there are no firm standaards yet, so some investigation is needed before committing to any particular technmology...an isochronous service is offered byu some x.25 switch manufactuerers, for instance (e.g. netcomm)). sorry to over-raise hopes... j. --------------- To: matsb@sics.se Cc: Piet.Beertema@mcsun.eu.net, wallace@rare.nl (Bruce Wallace), cpmu@rare.nl, davies@rare.nl, kalin@rare.nl, roll@sbd.stupi.se, ripe@ripe.net Subject: Re: Mis-information In-Reply-To: Your message of "Tue, 29 Sep 92 12:48:24 BST." <9209291148.AA03177@asia.sics.se> Date: Tue, 29 Sep 92 13:37:43 +0100 From: Jon Crowcroft <J.Crowcroft@cs.ucl.ac.uk>
Waht we do need is risk capital from tax payers to show new applications so taht the service providers will invest in higher bandwidth network solutions for mulitmedia mail and video conferencing.
Step 1 34 Mbps addtional bandwidth support to Ebone, maybe PTT telcomm is interested to prowide this for the same amount of money?
Step 2 Separate testbed to try new concepts and protocol structures
yes - we will need just these two steps to finalise work on the MICE project in late 1993. However, to start this project (from the day after tomorrow:-), we need: For those of you not aware, the EC has funded MICE (Multimedia International Conferencing for the Ec) to coordinate pilot services for audio, video, audio and shared whiteboard/editors between any interested EC and EFTA countries....at least France, Germany, Netherlands and Sweden + Norway are involved already. We will be using existing tools (e.g. vat, dvc, inria, videoconf,) for workstation conferencing and H.261 CODECs with packetizers and any other technology to link video conferencing roms facilities at Research and Educational Facilities. (A Packetiser is usually a sparcstation with hsi board). typically, this will entail IP (since much of the video/audio technology comes from the US< just like good networking technology), to carry packet video and audio - we hope to work with RIPE/RARE and with router and switch vendors to influence the production pof resource guarantees in ther network devices. End systems are already fine for audio, and shared applications in the Ebone environment. Video has not been extensively tried. If you are worred about being swamped with traffic, let me assure you that each user nation *must* have full approval end to end... obviously, the multicast facilities of the Mbone will be essential in optimising traffic (will EMPB provide multicast?). jon and just to agree on the sign-off:
Who would want to participate in an IP *pilot*, when we have a globe-wide, reliable, and well-managed IP *service* right behind our keyboards???
