The transmitted strategy of proxy cache based on segmented video

Abstract

Using proxy cache is a key technique that may help to reduce the loads of the server, network bandwidth and startup delays. Basing on the popularity of clients' request to segment video,we extend the length for batch and patch by using dynamic cache of proxy cache for streaming media. Present transmission schemes using dynamic cache such that unicast suffix batch, unicast patch, multicast patch, multicast merge and optimal batch patch by proxy cache based on segmented video. And then quantitatively explore 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. © IFIP International Federation for Information Processing 2004.
