Abstract: A hierarchical proxy deployment method includes: performing information collection and information interaction in a hierarchical proxy deployment architecture to obtain bandwidths and latencies of all inter-node communication links; and selecting an optimal proxy deployment solution from all feasible proxy deployment solutions based on the bandwidths and latencies of all the inter-node communication links. According to the method, a hierarchical proxy deployment architecture is used. An optimal proxy deployment solution is formed by selecting the optimal location and the optimal number of proxies for deployment to meet the transmission performance requirement of network applications in 5G/B5G networks. Therefore, transmission performance requirements are satisfied by a proxy deployment with a minimized number of proxies, thereby reducing network overheads and resource waste.

In this way, a user can quickly and conveniently obtain a measurement result of the physiological parameter, thereby improving the user's efficiency of obtaining information.

Abstract: A tape measure, a measuring device, and a measuring method are provided. The tape measure includes a first shell, a tape, an optical positioning assembly, and a first controller. The tape has one end mounted in the first shell and the other end extending out of the first shell and capable of moving in a first measuring direction relative to the first shell. An imaging sensor in the optical positioning assembly, when working, is capable of consecutively acquiring images of the tape in a moving process and then performing feature comparison on the images to determine a relative displacement of the tape moving in the first measuring direction in real time. Further, the controller of the tape measure is capable of determining, based on the relative displacement, a length by which the tape extends out of the first shell.
