With the advent of digital media , implementing reliable Video on Demand (VoD ) systems over the best effort Internet is a potential issue . Distributed streaming for Video on Demand presents a combination of two techniques . The first being Distributed Video Streaming using Multicast (DVSM ) [1] involves video streaming from multiple servers to overcome path congestion . The second technique , Asynchronous Hybrid mechanism for Video on Demand [2] implements segmentation -based periodic broadcast to effectively share network bandwidth . In this work we aim at providing path diversity of multiple senders and maximizing bandwidth sharing via multicast . We exploit alternate paths in case of congestion on a path while streaming segments of video . Distributed Streaming for Video on Demand uses similar algorithms as in DVSM and extends them to incorporate the segmentation -based periodic broadcast technique in Asynchronous VoD . Due to segmentation -based multicast and patching the system can provide low access latencies for requests arriving in an ad hoc manner .
This work introduces a robust Distributed Video on Demand Architecture by proposing modifications to the algorithms and mathematical relations in the base techniques . |
