The present invention relates to cache sharing system and method using clustering. The cache sharing system comprises: a cluster generation unit, if maintenance time indicating connectivity of each peer is greater than predetermined reference point time, making each peer form a cluster or join a cluster to generate a cluster; a cache sharing and managing unit, if the cluster generation unit generates the cluster, making peers, affiliated to the cluster, removing overlapped data and configuring a cache sharing environment for using several cache spaces like one cache space to share and manage the cache; and a query processing unit, if a query is requested, making a query peer process the query by checking whether the requested query data exists in an order of local caches thereof, 1-hop peer caches, cluster caches, and neighboring cluster caches. |
