Abstract: A data transmission method includes encapsulating, by a first device, first target data into N remote direct memory access (RDMA) packets according to an RDMA protocol, sequentially sending, by the first device, the N RDMA packets to the second device according to a packet sequence number (PSN) sequence of the N RDMA packets, where each of the N RDMA packets carries a first data write address, and the first data write address is an address for writing data in each of the N RDMA packets into the second device such that the second device directly obtains the first data write address in each RDMA packet from the RDMA packet, and writes the target data into storage space corresponding to the first data write address.

Abstract: A method and an apparatus for determining hash algorithm information for load balancing, and a storage medium are provided, to determine, based on first hash algorithm information of a first communication device and information about a first quantity of first ports of the first communication device, second hash algorithm information that is used for load balancing and that is of a second communication device. In this application, a load balancing device receives a first message, where the first message includes the first hash algorithm information of the load balancing mode of the first communication device and the information about the first quantity of first ports of the first communication device. The load balancing device determines the second hash algorithm information of the load balancing mode of the second communication device based on the first hash algorithm information and the information about the first quantity.

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.
