Abstract	Next Generation Network (NGN) is a broadband network that guarantees the quality of data transfers, independent of the lower transfer media, as real-time broadcasting services that are featured as a key service of the NGN require the multicast technique. Nevertheless, the existing IP multicast contains many limitations of application. Overlay multicast IP, an alternative to IP multicast, is a network studied widely for its ability to offer effective multimedia multicast transfers through flexibility and scalability. In this paper, we designed an agent for the destination network of each receiver and a manager that manages the entire overlay multicast topology for the source network where the media server is located. The manager and agent communicate with each other to assume the role of providing services based on network resource status. In this way, we can create a multicast environment that guarantees QoS in the NGN environment, which will be based on RACF (Resource and Admission Control Functions).
