【Abstract】 To reduce the blocking rate of three-layer network transmission,a three-layer network transmission method based on MPLSVPN architecture and AR technology is designed. The three-layer network transmission framework is established,and the data transmission queue model construction and dynamic refresh mechanism are designed. By using the resource reservation protocol,the end-to-end path is quickly established,and the adaptive multi-level queuing model is constructed. The AR technology is introduced,the refresh cycle is set,the dynamic refresh adjustment is carried out,the resource process is optimized,and the three-layer network transmission method is optimized. The experimental results show that the three-layer network transmission method based on MPLSVPN architecture and AR technology effectively lessens the transmission congestion rate,data delay and transmission service interruption rate,and meets the optimization needs of the three-layer network transmission method.更多还原
