Abstract (in Japanese) (See Japanese page) 
(in English) Recently, access loads on servers are increasing due to larger contents in content delivery network.Breadcrumbs(guidance information for locating a content cache) have been designed for reducing server loads and forming content oriented network autonomously in cooperation with cached contents in network. In addition, we proposed Breadcrumbs+ which solves Breadcrumbs’s problem that queries visit the same routers repeatedly with forming a loop. In this paper, we assume that users instead of routers cache contents and it will promote better load balancing, whereas existing methods assume that routers in the network cache contents. Moreover, we propose Active Breadcrumbs which provides higher cache utilization by spreading guidance information to neighbors of cache nodes more actively. Finally, we show the effectiveness of the proposed method by the extensive computer simulation.
