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.
Claims18
A multicast group establishment method in a fat-tree network, wherein the fat-tree network comprises N layers, the fat-tree network comprises multiple switching nodes, wherein a core switching node is on a top layer, and each core switching node manages multiple multicast group addresses assigned by a management device of the fat-tree network;
- and the method comprises:
- 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, wherein the join request is used to request to make the network node join the target multicast group, to establish 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, wherein
- the join request is self-routed from a bottom-layer switching node of the fat-tree network to the management switching node of the target multicast group in sequence according to the address of the target multicast group.
A multicast group establishment method in a fat-tree network, wherein the fat-tree network comprises N layers, the fat-tree network comprises multiple switching nodes, a top layer is a core switching node, and each core switching node manages multiple multicast group addresses assigned by a management device of the fat-tree network;
- and the method comprises:
- receiving, by the core switching node, a join request sent by a network node according to an address of a target multicast group, wherein the join request is used to request to make the network node join the target multicast group, to establish the target multicast group, and the address of the target multicast group is managed by the core switching node, wherein
- the join request is self-routed from a bottom-layer switching node of the fat-tree network to a management switching node of the target multicast group in sequence according to the address of the target multicast group.
A network node, wherein a fat-tree network comprises N layers, the fat-tree network comprises multiple switching nodes, a top layer is a core switching node, and each core switching node manages multiple multicast group addresses assigned by a management device of the fat-tree network;
- and the network node comprises:
- a memory comprising instructions, and
- one or more processors in communication with the memory, wherein the one or more processors execute instructions to:
- configured to send, according to an address of a target multicast group, a join request to a management switching node of the target multicast group, wherein the join request is used to request to make the network node join the target multicast group, to establish 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, wherein
- the join request is self-routed from a bottom-layer switching node of the fat-tree network to the management switching node of the target multicast group in sequence according to the address of the target multicast group.
