Hk/T : A Novel Server-Side Web Caching Strategy for Multimedia Applications
Server-side Web caching is an important technique used to reduce the User Perceived Latency (UPL). In large-scale multimedia systems, there are many Web proxies, connected with a multimedia server, that can cache some most popular multimedia objects. Multimedia objects have some particular characteristics, e.g., strict QoS requirements. Hence, even some efficient conventional caching strategies based on cache hit ratio, meant for non-multimedia objects, will confront some problems in dealing with the multimedia objects. If the authors consider additional resources of proxy besides cache space, say bandwidth, they can readily observe that high hit ratio may deteriorate the entire system performance.
