....request can quickly deplete server resources. Recent work has focussed on leveraging the multipoint data distribution facility of the Internet called multicast [20] to reduce the server and network load [18] 33] 1] 2] 76] 11] 38] 31] 39] 40] 42] 54] 9] 25] 32] 37] [46], 55] 64] 67] 26] 27] For example, a simple scheme is to aggregate client requests for the same media file that are separated by a small time interval into one group, and serve them by a single multicast stream [18] As mentioned above, a requirement of many scalable streaming ....

....changes, thus limiting the merging capability of these schemes. Significant performance gains can be achieved by leveraging additional available client bandwidth and storage space, as demonstrated by the recently proposed periodic broadcast protocols [76] 1] 38] 39] 31] 42] 54] 37] [46], 55] 64] patching [11] 9] 40] 32] 67] and hierarchical multicast stream merging [25] 26] 27] A. Periodic Broadcasts Periodic broadcast protocols divide a media object into K segments with relative lengths l 1 ; l 2 ; l K . Each segment is periodically broadcast ....

....problem. Saparilla et al. proposed a protocol in [12] we will call it VBR B) using the segmentation scheme in FB and applied the techniques of GoP smoothing, server buffering and client prefetching to improve its performance. Another protocol, the Trace Adaptive Fragmentation (TAF) proposed in [13] is an improvement of VBR B to take into account the trace of each video and try to obtain lower aggregate bandwidth by comparing possible combinations of feasible video schedules. In [11] Paris proposed a VBR broadcasting protocol (VBHB) based on the cautiousharmonic protocol. This protocol does ....
