Abstract: Provided are a multicast traffic transmission method and apparatus, a communication node and a storage medium. The multicast traffic transmission method includes the following. A first forwarding entry is determined, where the first forwarding entry includes Bit Indexed Explicit Replication (BIER) information of an Autonomous System Border Router (ASBR); multicast traffic is acquired; and the multicast traffic is encapsulated based on the first forwarding entry, and a BIER packet is determined and transmitted.

Abstract: Embodiments of the present disclosure provide a network logical layering method based on Routing In Fat Tree (RIFT) protocol, a network logical layering device, a network device and a storage medium. By exchanging Link Information Element (LIE) packets and Topology Information Element (TIE) packets with other devices, a network device can enable the other devices in the network to know a topology supported by the present device and to know neighbor information and Metric information of the present device in the supported topology, and the network device can also know the topologies supported by the other devices in the network and the neighbor information and the Metric information of the other devices in the corresponding topologies. Thus, the device can calculate a topology route corresponding to the topology supported thereby.

Abstract: Provided are a multicast cross-domain method, device and system, and a computer readable storage medium. The method includes: dividing nodes in each domain of a multi-domain network into a multicast proxy nodes and a common nodes; sending, by the common nodes, a subscription request to a multicast source node outside the each domain through the multicast proxy nodes in the each domain; sending, by the multicast source node, a bit indexed explicit replication (BIER) multicast message obtained through BIER encapsulation to the multicast proxy nodes; and sending, by the multicast proxy nodes, the BIER multicast message to the common nodes.
