In-network caching is one of the key aspects of content-centric networks (CCN), while the cache replacement algorithm of LRU does not consider the relation between the contents of the cache and its neighbor nodes in the cache replacement process, which bring worthless cache block in the cache and reduce the efficiency of the cache. An enhanced LRU cache replacement strategy has been proposed, which can replace the cache block in time that is not requested from other nodes and improve the rate of effective utilization of the cache space. Simulation results show that the A-LRU strategy increases cache hit rate, shortens the data request delay and improves overall network performance, verifies the validity of the A-LRU strategies in CCN.
