System and method for controlling multicasting service

摘要

In a system and method for guaranteeing quality of service (QoS) of a multicasting service, when a multicasting source or a receiving terminal is newly registered, or a router or the receiving terminal leaves an existing multicasting group, a topology and a resource state of a network is retrieved, and a determination is made as to whether to provide a new multicasting service based on the retrieved network resource state. Thus, multicasting-based high-quality multimedia service can be provided to users.
