Abstract

The invention provides a multicast method, a multicast relay device and a multicast system which relate to a wireless local area network. The method comprises the steps of receiving multicast service data forwarded by an access point (AP) through a unicast transmission protocol; and transmitting the received multicast service data to a multicast group through a multicast transmission protocol.

Description

technical field [0001] The present invention relates to the field of communication, in particular to the field of wireless local area network communication, in particular to a multicast method, a multicast relay device and a multicast system related to a wireless local area network. Background technique [0002] With the rapid development of wireless local area network technology, wireless local area network (WLAN) is more and more applied to homes and enterprises. The use of traditional wired network connections has become less and less, and many homes or businesses no longer deploy wired LANs, but use WLAN to cover the entire home or business. [0003] The existing 802.1111n / 11ac protocol supports ordinary Internet surfing very well, and the physical layer rate can reach Gigabit at the highest, and users can feel no delay. However, the support for video services using multicast is weak. The 802.11 protocol stipulates that there is no ACK and retransmission protection mec...
