Title: METHOD FOR REALIZING MULTICAST AND RELEVANT NETWORK DEVICE
Abstract:
Disclosed are a method for realizing multicast and a relevant network device used for reducing a network bandwidth and an out-stream load of a live stream in a network transmission process. The method, according to the embodiment of the present application, comprises: a live service server sending a live stream injection request to a multicast resource management server; the live service server receiving a live stream injection response sent by the multicast resource management server; the live service server sending, according to the address of a live stream injection node, a live stream injection instruction to the live stream injection node; the live service server receiving a pushed stream address sent by the live stream injection node; and the live service server notifying a live source of sending, according to the pushed stream address, a live stream to the live stream injection node, such that the live stream injection node, corresponding to the pushed stream address, uses a multicast IP to carry out multicast for the live stream.
