摘要

For broadcasting a file to communication processing systems E, F, H, I, J and K, a communication processing system A sends the file and destinations E, H and I to the communication processing system B, and the file and destinations F, J and K to the communication processing system C. Of the sent destinations E, H and I, the communication processing system B delivers the file to the communication processing system E for which the system B is responsible for delivering the file, and for the other destinations, sends the file and the file destinations H and I to the relaying communication processing system D.
