Structured Partially Caching Proxies for Mixed Media

News on demand features user interaction, interdependent media and is used by different client types. These requirements are not yet accommodated by a single solution. We address this issue by utilizing a priori knowledge about news articles’ structure encoded in a presentation plan. Using this, we investigate the gains that knowledge about structure can have for a caching proxy. Our simulations show that structured partial caching of media object segments achieves a higher byte hit ratio compared to a non-structured caching scheme when access patterns follow a Multi-Selection Zipf distribution.
