[0004] In recent years, cloud desktop applications have become increasingly popular. Cloud desktop usage places high demands on the latency and reliability of audio and video transmission. Figure 1 shows a cloud desktop network configuration. Cloud desktop client terminals directly connect to a cloud access gateway (CAG) via the internet, communicating with the cloud desktop server through the CAG. This networking approach selects a CAG based on a fixed configuration, but the CAG selected based on this fixed configuration is not necessarily the optimal one. When network quality fluctuates, there is a possibility of lag.
