Abstract:
The present technology provides a system, method and computer readable medium for steering a content request among plurality of cache servers based on multi-level assessment of content popularity. In some embodiments a three levels of popularity may be determined comprising popular, semi-popular and unpopular designations for the queried content. The processing of the query and delivery of the requested content depends on the aforementioned popularity level designation and comprises a acceptance of the query at the edge cache server to which the query was originally directed, rejection of the query and re-direction to a second edge cache server or redirection of the query to origin server to thereby deliver the requested content. The proposed technology results in higher hit ratio for edge cache clusters by steering requests for semi-popular content to one or more additional cache servers while forwarding request for unpopular content to origin server.
