Several multicast bandwidth sharing techniques have been proposed in the literature to provide more scalability to multimedia servers. These techniques are often analyzed in terms of the average bandwidth requirements they demand to satisfy client requests. However, average values do not always provide an accurate estimate of the required bandwidth.(More)
The deployment of a high-quality VoD service at low-bandwidth cost is still far from widespread. Moreover, DVD-like operations have recently become essential for applications using this type of service. Focusing on interactive access, this paper proposes the Efficient Interactive Patching (EIP) and Interactive Merge (IM) schemes. The former is an(More)
