Co-existing static and dynamic ip multicast

A providing static and dynamic AND multi-broadcasting system and method. A with the static and dynamic IP broadcasting coexistence to broadcasting static from the concept. Multicast dynamic range of broadcasting portion is static group at least D layer AND addresses, and arranged on the router. When the router receiving PIM or the IGMP message, wherein the allocation method of determining information of radio electrostatic is clamped. And the group of the static to play group clamped, a router does not made of PIM protocol to disseminate the information the upstream router, is only strip or a separation router is interface. And the group is not radio electrostatic is clamped, a router recognizes the information is the tendency to broadcasting device, method for PIM or the IGMP protocol and usual. A invention is used for playing TV, a groove for clamping low-end or normally for playing of the substrate according to static, AND the user access energy or the lower groove is arranged or connects the whole layer short-path tree, and channel according special or normally does not made of broadcasting base to effectively to move in a router resource with dynamic IP.
