Abstract: A cloud computing data center system includes a first server, a second server, a cloud management platform, and a switch. The first server includes a first computing node and a first distributed gateway. The first distributed gateway receives a management packet sent by the cloud management platform. The first distributed gateway records network information of the second VLAN. A first virtual machine sends a first service packet that carries service data to a second virtual machine. The first distributed gateway receives the first service packet, generates a second service packet by modifying the first service packet based on the network information of the second VLAN, and sends the second service packet to the switch. A second distributed gateway receives the second service packet forwarded by the switch, and sends the second service packet to the second virtual machine. In this way, network reliability may be improved.

Abstract: A force measurement system includes: a grinding arm and a force receiving device, the force receiving device being fixed on its one side and configured to receive a force from the grinding arm; a load cell, which is fixed on the force receiving device and configured to detect the force received by the force receiving device; and a grinding disk, which is fixed on the grinding arm that applies the force to the force receiving device through the grinding disk. The embodiments of the present application facilitate accurate acquisition of a force acting upon a grinded object during actual grinding.

Abstract: Force measurement system is provided. It includes: a grinding arm and a stressed layer, the stressed layer being configured to bear a force from the grinding arm; a base and a plurality of elastic bodies, the elastic bodies being fixed between the stressed layer and the base; a deformation sensor, configured to detect deformation of the elastic bodies; and an analysis device, configured to obtain the force on the stressed layer according to a detection result of the deformation sensor and an elastic constant of the elastic body.

Abstract: A dialing test method, a dialing test system, and a computing node relate to the network field. In this method, a dialing test system respectively creates a two dialing test ports on two computing nodes, where both Internet Protocol (IP) addresses of the two dialing test ports are IP addresses of a dialing test network, and the dialing test network does not overlap a service network of a virtual machine (VM). The dialing test system separately deploys respective dialing test resources for the two dialing test ports, and the dialing test resources does not overlap a resource of the VM on the two computing nodes, and the dialing test system triggers a dialing test procedure such that a dialing test task is executed between the two dialing test ports using the dialing test resources.
