Audio IP Multicast Experiment _____________________________
1. Carl Mamalud, author of several technical textbooks on the Internet and Internetworkgin technology, has proposed to initiate an audio broadcasting service over the Internet, using IP Multicasting techniques.
2. The format of the audio would be SPARC compatible u-Law encoded audio over IP. This data would be sent out over the Multicast Backbone being installed across the Internet (MBONE).
3. A weekly interview program would be produced, using professional production techniques, and would offer interviews with prominent computer industry figures. The format would initially be broadcast only to the receiving sites on a weekly basis.
4. This technique would offer the first large scale technical "Proof of Concept" test of IP multicasting, a key foundation of future multimedia network transports.
5. As a next step, the service would be expanded to allow IP multicasting of questions back to the broadcast site, allowing interaction over these large, wide area networks to occur.
6. The problems raised by having systems join and drop out of multicast groups are of singular importance to the high speed and multimedia infrastructure developers, in that the issues of security, administration and network topolgy all affect the mechanisms which need to be constructed.
7. Using this effort as a validation mechanism for our implementation of Multicasting and as a testbed designed to reveal new problems in the IP area would provide Sun with the unique opportunity to have rapid turnaround of results and wide exposure to wildly varying network conditions.
8. The next step in this effort would be to send video using the Multicast mechanism, leading to similar problem discovery and resolution.
9. The research benefit, combined with the exposure which Sun would gain in the Internet community by supporting these efforts does, in my opinion justify the expenditure of expense monies to allow the project to take place.
10. In addition, the Internet Engineering group in SunSoft has agreed to split the cost with us, with each group funding the project for $25k.
