PURPOSE: A method for effectively distributing contents in a CDN(Contents Delivery Network) is provided to effectively and reliably distribute contents by a CDN provider or a CP(Contents Provider), to reduce a network bandwidth while configuring a CDN, thereby minimizing an investment cost. CONSTITUTION: A CP supplies distributed contents information to a contents distributor(S210). The contents distributor checks whether distributed contents exist in the CP(S211). If so(S212), the CP reads the distributed contents, and stores the distributed contents in a staging server(S215). The contents distributor transmits the stored distributed contents to edge servers(S216). The distributed contents are inputted to a distributed agent before being stored, to carry out an integrity check. The distributed agent supplies integrity check results to the contents distributor(S217). The contents distributor decides the check results(S218), and stores the distributed contents with integrity in each edge server(S219). |
