The information obtains the corresponding virtual desktop data from the cloud desktop server, and sends the obtained virtual desktop data to the terminal in a multicast manner. At this point, the proxy terminal can initiate a communication connection to the cloud desktop server.

The indirect multicast communication request in this step may also include the information about the virtual desktop data to be obtained, and if the indirect multicast mode is determined according to the detection result, the multicast mode may also be sent to the cloud desktop server (in this case, In the indirect multicast mode, the multicast mode control message may include information about the virtual desktop data to be acquired. At this time, the cloud desktop server may initiate a communication connection to the proxy terminal, and send the corresponding virtual desktop data to the proxy terminal, and the proxy terminal sends the virtual desktop data to the terminal in a multicast manner.

When the detected transmission delay time value is greater than the preset transmission delay threshold, the network environment is poor. For example, the network environment may be in a cross-network segment. Indirect multicast mode is adopted. Otherwise, direct multicast mode is determined.

Method 2:

Detecting the packet loss rate of the network where the terminal is currently located, when the detected packet loss rate is greater than the default When the packet rate threshold is set, the network environment is poor. For example, the indirect multicast mode is determined. Otherwise, the direct multicast mode is adopted.
