Embodiment Construction
[0043] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0044] As shown in Fig. 1, the transmission structure of the present invention is composed of any number of media forwarding nodes deployed in many IP multicast islands and a unique forwarding node controller. Among them, the media forwarding node accesses user terminals under the control of the forwarding node controller, including multicast users and unicast users. The multicast island where the only forwarding node controller is deployed is called the main multicast island. Known as neighbor multicast islands, media forwarding nodes can be configured with multiple network interfaces, and each network interface can be connected to the same multicast island or different multicast islands.
[0045] The entire transmission structure is a two-layer overlay network structure: the first layer, multiple media forwarding nodes are distributed in each multica...
