The batch patching algorithm using dynamic cache of proxy for streaming media

The proxy cache for streaming media is the important method to economize the resources of the Internet. The cache policies influence the effect for proxy cache. In this paper, based on the client´s request rate, cached the video based on segment, we proposed that the policies for batch, patch and batch patching using dynamic cache. The policies of batch and batch patching using dynamic cache based on segment enlarge the width of the batch and patching. It combines dynamic cache based on segment with the excellence of patch. Presented that allocation relation of the cache between the batch and patch using dynamic cache, and assured that batch patching using dynamic cache of proxy based on segment is optimal.
