<p>The present invention discloses a method and apparatus for multicast management of user interface in a network access device (20), which comprises setting a user multicast information table (23) for the user interface in the network access device (20), IGMP protocol processing unit (21) obtaining the user identification information from a user IGMP message, retrieving and updating the user multicast information table (23) based on types of multicast messages; checking the user multicast information table (23) of the user interface when multicast resources of the user interface are not sufficient, immediately terminating the multicast GSQ process and directly performing quick-leaving when the user multicast information table (23) of a multicast group is empty, in conjunction with use of items of multicast state. The present invention can greatly enhance speed and performance of switching for multicast channels of the network access device (20).</p> |
