A data transfer method and a switching equipment, the corresponding relation between the service instances and the multicast addresses is set in the network, the node receives the service instance data message need to be transmitted using the broadcast mechanism, then determines the service instance which the service instance data message belongs to, and searches the multicast address which the service instance which the service instance data message belongs to is corresponding to from the corresponding relation, and then, transmits the service instance data message by making the searched multicast address as the destination address. The network includes the Ethernet and the IP network, the multicast address includes the multicast MAC address, the multicast IP address and so on. The embodiments of present invention transform the broadcast mechanism to the multicast mechanism and control the generation of the broadcast storm effectively, the link failure only may affect the data messages transmitted through the link, the delay problem of the generation tree protocol is avoided, the requirements of the telecommunication services are satisfied, the stability and reliability of the network transmission are increased.
