Abstract

The invention relates to a method and device for adjusting a multicast physical sending rate. The method comprises the following steps that a plurality of multicast physical sending rates and a plurality of multicast packet loss probability threshold value intervals are configured in advance; statistical information of all target terminals of the same multicast stream for receiving the multicast stream during the first preset time is obtained, and the packet loss probability from the multicast stream to at least two target terminals is obtained according to the obtained statistical information of the at least two target terminals; the multicast physical sending rate of the multicast stream is adjusted according to the multicast packet loss probability threshold value interval of the obtained maximum packet loss probability and the pre-configured multicast physical sending rates, and the multicast stream is sent according to the adjusted multicast physical sending rate within the second preset time. According to the adjusting mode of the multicast physical sending rate, the transmission success rate of the multicast stream can be improved.

Description

technical field [0001] The invention relates to the technology in the field of network communication, in particular to a method and a device for adjusting the multicast physical transmission rate. Background technique [0002] Wireless Local Area Networks (WLAN), as an access technology for network terminals, provides great convenience for users to access the Internet. Applications of WLAN include wireless office, wireless teaching, Internet of Things, wireless medical care, etc. . In a multicast network, if a sender transmits the same data to multiple receivers at the same time, it only needs to copy a copy of the same data packet. Multicast (Multicast) technology improves the transmission efficiency of network data and reduces the backbone network The possibility of congestion. [0003] As we all know, due to the impact of signal attenuation, collision, interference and other factors on the packet transmission in the wireless local area network, the failure rate of the p...
