[0035] A method for changing the IPTV broadcast address pool based on SDN technology described in the present invention, combining figure 1 As shown, the method includes the following steps:
[0036] (1) Add SDN switching equipment SW between the multicast source of the existing network and the multicast transmission switching network A , the uplink port is connected to the multicast source, and the downlink port is connected to the multicast transmission switching network;
[0037] (2) Use a PC and SDN switching device SW ADirect connection, as a multicast IP address change server Ser B ;
[0038] (3) According to the user-defined IP change rule Am, according to the SDN switching equipment SW A Provided operation command, write multicast IP address pool {IP 0 , IP 1 , IP 2 , IP 3 ,...IP n}Changed operation command set C to form IP change script D;
[0039] (4) Change the server Ser in the multicast IP address B Set the execution time rule T on the change script D ...
