Title: A Light-Weight Repair Protocol for the Loss-Free Recording of MBone Sessions.

Abstract: With the increasing popularityof MBone conferences, the need arose to archive the multimedia streamsof these conferences. Like all network applications, a conferencerecorder is subject to packet loss, which introduces gaps intorecorded media streams. Such gaps degrade the playback quality of anarchived media stream or even disable the correct playback. In thispaper, we present a novel scheme for the loss-free recording of mediastreams. In contrast to existing systems that require the placement ofrecording caches within the network, our approach enables anend-to-end system design. We present a detailed protocol analysis thatconfirms the validity of our approach.
