Embodiment Construction
[0049] The core idea of the present invention is to realize the smooth docking of BIDIR PIM and PIM SM by implementing BIDIR PIM Relay technology on the RP device supporting PIM SM, without requiring all devices in the PIM SM domain to support the BIDIR PIM protocol, thereby finally realizing The flexible deployment of BIDIR PIM and PIM SM makes the BIDIR PIM protocol widely used.
[0050] The transmission method of a kind of multicast data that the present invention proposes is applied in the multicast network that comprises BIDIR PIM domain and PIM SM domain, and needs to carry out the transmission of multicast data between described BIDIR PIM domain and PIM SM domain, in The multicast network includes a multicast source, a receiver, a BIDIR PIM Relay, and an RP in the BIDIR PIM domain, wherein the BIDIR PIM Relay is an RP in the PIM SM domain, and the BIDIR PIM Relay is connected to the BIDIR PIM Relay Device connections in the BIDIR PIM domain described above, such as ...
