建议建立多条udp连接以解决运营商对udp的qos
虽然在理论上udp在速度上相比tcp更有优势，但是当运营商对udp进行qos，tcp比udp更好。可惜目前tcp的p2p穿透还没有成果，所以只能建立多条udp连接改善速度

It is recommended to establish multiple udp connections to solve the operator’s qos to udp
Although in theory udp is more advantageous than tcp in terms of speed, when the operator performs qos on udp, tcp is better than udp. Unfortunately, the p2p penetration of tcp has not yet achieved results, so we can only establish multiple udp connections to improve the speed
