摘要When a radio access network (RAN) environment cannot handle the tremendous
mobile data traffic, users may experience degraded or declined services. To help process
the large number of user video requests in RANs, a content delivery network (CDN)
architecture has been recently introduced, which establishes a number of cache servers
outside the source server for users to get the needed data from the nearest cache server.
To upgrade the performance of a wireless CDN, this paper presents a new caching
strategy based on analytical results of real user video request traces and specific caching
considerations for videos with different popularity degrees. The new strategy first caches
videos with high popularity to all helpers and then caches those with low popularity to the
remaining helper storage to enhance the overall request hits. Performance evaluation
exhibits that, when compared with other caching strategies, our new strategy is able to
yield better request hits with low complexity and average delay time.
