Panel3: Multicasting & Real-Time Applications and the Future of the Web
Co-Chair: Jaromir Likavec
(Participating from Paris)

Computer Graphics Center,
Darmstadt, Germany


Topic: Multicasting from the International World Wide Web Conferences, Past and Present


Evolving from a purely academic event,the International WWW Conference has developed into a get-together of thousands of users from a wide variety of application domains. MBONE multicasting from International WWW Conferences has also changed from an occasional test multicasting to the event that is fully integrated into the Conference. One cannot even imagine the WWW Conference without multicasting.

MBONE multicasting has been organised at each WWW Conference. The complexity and the material multicast has grown with each conference At the first Conference only occasional sessions were multicasted. At the second conference in Chicago, one MBONE machine was used from the begining to the end. At the 3rd and 4th conferences two parallel streams has been organized. In Paris we are multicasting on two channels. Multicasting from the conferences is also used as a testbed for the new tools. In Darmstadt we used webcast for multicasting html slides. In Paris we are using mcm for this purpose. In Boston reliable audio tool (rat) was used as an alternative to visual audio tool (vat).For the first time, at this Conference we are sending audio and video stream for PC/mac over a Cu-SeeMe reflector in Norway. A subset of sessions that were multicast were recorded on the video tape. These tapes were rebroadcast the same day for the another hemisphere on the Third and Fourth conference. Some sessions from the Third conference are available as audio/video/slides on demand.

This panel, along with other events will lead to integration processes between IETF activities, WWW Consortium and all the progressive people in the world in building the global information system.

Equipment

SUN Sparc computers (SS20/SS5/SS10/Ultra) were used on the past conferences for multicasting. Computers were running under Solaris and were sponsord by SUN Microsystems.
