Proxy-Based Distribution of Streaming Video Over Unicast/Multicast Connections
Overview This paper addresses the problem of efficiently streaming a set of heterogeneous videos from a remote server through a proxy to multiple asynchronous clients so that they can experience playback with low startup delays. They developed a technique to analytically determine the optimal proxy prefix cache allocation to the videos that minimizes the aggregate network bandwidth cost. The paper integrated proxy caching with traditional server-based reactive transmission schemes such as batching, patching and stream merging to develop a set of proxy-assisted schemes. Then they quantitatively explored the impact of the choice of transmission scheme, cache allocation policy, proxy cache size, and availability of unicast versus multicast capability, on the resultant transmission cost.
