<p>A method and system of establishing an optimal path in a multicast receiving end switching scenario. The method comprises: a target mobile access gateway (MAG) of a multicast receiving end (MN) acquiring multicast state information of the MN from a source MAG of the MN or a local mobile anchor (LMA) to which the source MAG of the MN belongs; establishing, according to the multicast state information of the MN, a multicast tunnel with an MAG to which a multicast source (MN-S) of the MN belongs; and the MAG to which the MN-S belongs sending a multicast message of the MN-S to the target MAG of the MN through the multicast tunnel. The method of establishing an SPT path provided in this solution can improve the routing efficiency during switching of a multicast receiving end and the performance of mobile multicast.</p> |
