Abstract
A multicast delay diagnosis method is provided, where the method includes sending, by a terminal device, a first domain name resolution request to a network node; receiving a first multicast test address returned by the network node; sending a first multicast test join request to the network node by using the first multicast test address, and recording a time point for sending the first multicast test join request; receiving a first packet returned by the network node, and recording a time point for receiving the first packet; calculating, according to the time point for sending the first multicast test join request and the time point for receiving the first packet, a first delay caused when the terminal device joins a multicast test group of the network node; and determining multicast network quality according to the first delay.
