1. A multicast system, comprising:

  • a multicast service module; and

    a multicast processing module for subscribing to the multicast service module;

    wherein the multicast service module sends a subscribe response to the multicast processing module, and transmits data to the multicast processing module via a unicast frame; and

    the multicast processing module further identifies whether the multicast processing module itself is a data initiator according to the subscribe response, and receives the data from the multicast service module in a multicast mode if the multicast processing module is the data initiator, or receives the data from the multicast service module, by discarding unnecessary data and only keeping required data, in a promiscuous mode if the multicast processing module is not the data initiator.
