upLoss property
Upstream Packet Loss Rate, in percentage (%) - The smaller the value, the better. If upLoss is 0%, it means that the network quality of the upstream link is excellent, and the data packets uploaded to the cloud are not lost. If upLoss is 30%, it means that 30% of the audio and video data packets sent by the SDK to the cloud are lost in the transmission link.
