Abstract: A communication method is suitable for use in a network architecture including using a software defined network (SDN) protocol and a legacy network protocol, and includes the following steps. A first sub-domain manage unit of a first SDN sub-domain receives a connection request message corresponding to a multicast source from a client. The first sub-domain manage unit transmits a join request message to a main router of a legacy network domain connected to the first SDN sub-domain when determining that the multicast source is not in the first SDN sub-domain. The first sub-domain manage unit transmits the connection request message to a first domain manage unit of a first SDN domain when the main router determines that the multicast source is not in the legacy network domain. A communication path is established between the client and the multicast source when a location of the multicast source is obtained.
