<p>PROBLEM TO BE SOLVED: To revise dynamically a multi-cast connection group. SOLUTION: The system has a registration means M3 that registers an object address and channel information of a user of the object address subject to connection registration request to an object user connection management table M2 pointed out by a pointer of a transmission user registration table M1 by a connection registration request from a multi-cast service contract user and a transmission means M4 that sends user data to the user of the object address of the object user connection management table M2 pointed out by a pointer obtained by searching the transmission user registration table M1 based on supply of user data from the multi-cast service user. Thus, multi-cast communication is conducted to the users of pluralities of object addresses to be registered and the multi-cast connection group is dynamically revised.</p> |
