Caching techniques for streaming multimedia over the internet,” Bell Laboratories

Abstract—Existing solutions for streaming multimedia in the Internet do not scale in terms of object size and num-ber of supported streams. Using separate unicast streams, for example, will overload both network and servers. While caching is the standard technique for improving scalabil-ity, existing caching schemes do not support streaming me-dia well. In this paper, we propose a complete solution for caching multimedia streams in the Internet by extending ex-isting techniques and proposing new techniques to support streaming media. These include segmentation of streaming objects, dynamic caching, and self-organizing cooperative caching. We consider these techniques in an integrated fash-ion. We implemented a complete caching architecture called SOCCER using the network simulator ns-2 and evaluate the effectiveness of each proposed technique and compare them to alternative caching solutions.
