DISC: Dynamic Interleaved Segment Caching for Interactive Streaming
Streaming media objects have become widely used on the Internet, and the demand of interactive requests to these objects has increased dramatically. Typical interactive requests include fast forward and direct jumps. Unfortunately, most of existing streaming proxies are designed for sequential accesses, and only a few solutions have been proposed to maintain additional data structures in the proxy to support some interactive operations (such as fast forward) other than jumps, which are among the most common interactive requests from the clients. Focusing on interactive accesses, in this paper we present an analysis of streaming media workload collected from thousands of broadband users hosted by a major ISP. Our analysis shows that jump accesses (48%) and pauses (51%) are the dominant client interactive requests and that jump accesses often suffer serious delays due to slow buffering through the network. To support jump accesses effectively, we further propose a novel caching algorith...
