PROBLEM TO BE SOLVED: To distribute membership information about a participant computer system which participates in a multi-party conference session. SOLUTION: A link database comprises one or a plurality of link state records for discriminating a participant computer system from a list of neighboring computer systems logically linked to the participant computer system. When a new computer system participates in the multi-party session, the change such as participation is reflected on the link database of a corresponding neighboring computer system. Since the neighboring computer systems exchange link databases each other, the change is eventually propagated to all participant computer systems. Thus, the participant computer systems continuously transit toward such stable state as each participant computer system is aware of other participant computer systems and logical links related to them.
