Abstract
The invention relates to a method of selecting a RTP (Real Time Protocol) element in a dynamic multicast tree for a multimedia conference and a record medium recorded with a program for realizing the method that can be read by computers, and in particular to a method of selecting a RTP element in a dynamic multicast tree for distributing an overload applied to the root node of the dynamic multicast tree and a record medium recorded with a program for realizing the method that can be read by computers. The method comprises the steps of: (a) confirming in the RTP element if the RTP element is subscribed to the dynamic multicast tree that a new multimedia terminal wants to join; (b) if the RTP element is not subscribed to the dynamic multicast that the new multimedia terminal wants to join according to a result of the confirmation in the step (a), joining in the RTP element the root node of the dynamic multicast tree and then causing the new multimedia terminal to join the dynamic multicast tree of a multimedia conference system; and (c) if the RTP element is subscribed to the dynamic multicast that the new multimedia terminal wants to join according to a result of the confirmation in…
