Abstract: A multicast group establishment method in a fat-tree network is disclosed, the method includes: sending, by a network node according to an address of a target multicast group, a join request to a management switching node of the target multicast group, where the join request is used to request to make the network node join the target multicast group, and the management switching node of the target multicast group is a core switching node to which the address of the target multicast group belongs. The fat-tree network includes multiple switching nodes, a top layer is a core switching node, and each core switching node manages multiple multicast group addresses.
