<p><P>PROBLEM TO BE SOLVED: To flexibly perform correspondence, in response to the change of a distribution group with a simple configuration, and without requiring a large scale of configuration, such as a server device. <P>SOLUTION: A communication apparatus 100 generates group information by a multicast group management 11, based on destination information designated by a user. A multicast address generator 12 generates a multicast address, based on the group information. When the communication apparatus 100 is at a transmission side, a network I/F 13 adds the generated multicast address to data and transmits it to a network NW. When a communication apparatus 200 at a reception side, a network I/F 23 is indicated to receive data to the generated multicast address. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
