Method and system for creating data transmission path for providing n:n communication service

The present invention relates to provide a multi-communication service-to-multipoint in a communication environment in a many-to-many, consisting of a multi and a plurality of edge domains including a plurality of mobile agent to forward the multicast data, the core domain connecting the edge domain, a session manager for multi relates to a method and system for configuring a transmission path of multicast data, the session manager to join in the formed user of the communication service-to-multipoint, and wherein to form a session for the communication service many-to-many from the session manager to the session, and controlling the withdrawal, and wherein the managing information relating to the communication service a many-to-many, the plurality of agents perform the join / leave the formed session by using the information received from each of the session manager, to relay the data by configuring the data transfer path, wherein By edge, and monitoring and repair errors in the core domain it can provide a many-to-many communication services that can minimize the change of the current Internet device. Many-to-many communication services, multicast data transmission path, the core domain, the edge domain, a core multicast agent (Core Multicast Agent, CMA), the edge multicast agent (Edge Multicast Agent, EMA), wire manager (Session Manager, SM) .
