The invention relates to a network switching method and device of a virtual machine, computer equipment and a storage medium. The method comprises the following steps: monitoring the network state of a main network under the condition that a virtual machine uses the main network to carry out network communication; a communication link of the main network comprises a virtual switch in communication connection with the virtual machine, a network service component in communication connection with the virtual switch and a physical switch in communication connection with the network service component; switching the communication network of the virtual machine to a standby network when monitoring that the main network is in the abnormal network communication state; the standby network is in communication connection with the physical switch through a user mode provided by the fast simulator; and the fast simulator is used for simulating and generating the virtual machine. By adopting the method, the network reliability of the virtual machine can be improved, and the high availability of the virtual machine is further improved.

The invention discloses a device networking method and device, a device, a storage medium and a product, and the method is applied to a first device, and comprises the steps: obtaining one or more candidate devices with available device link states; selecting at least one target candidate device from the one or more candidate devices according to a service demand of a to-be-processed service; under the condition that a logic channel of a first transmission channel is in a non-working state, initiating a transmission channel establishment process to the target candidate equipment, and initiating the transmission channel establishment process to the target candidate equipment, so as to access a network through the established first transmission channel; the first transmission channel is a transmission channel between the first device and the target candidate device. By adopting the embodiment of the invention, a multi-link cooperative networking implementation mode can be provided for a field-level short-distance wireless communication network, and the equipment transmission reliability and the networking reliability are higher.

This application relates to the field of optical fiber communication network technology and discloses a communication network optimization method based on optical fiber sensing and the importance of carried services. The method includes: periodically injecting optical time-domain reflectometry (OTDR) sensing signals into all spare fiber cores; calculating the current loss and crosstalk values ​​of each spare fiber core based on the backscattered signals; monitoring and analyzing the service flows carried on the operating fiber cores; determining the current service importance level of each service flow according to a power communication service type-level mapping table; when an operating fiber core fails, selecting and removing target fiber cores from the set of available spare fiber cores in descending order of service importance level according to fiber core selection rules, forming a mapping relationship; generating and sending port switching control commands based on the mapping relationship to migrate services and updating the network routing table. This application achieves refined perception of spare resources and intelligent protection of differentiated service needs during communication network fault recovery.

The invention discloses a networking control method and device, electronic equipment and a storage medium, and is used for solving the problems of high networking cost, low networking reliability and low networking applicability. The networking control method comprises the steps that a main network device receives an address allocation request sent by a slave network device, and the main network device and the slave network device are selected according to respective corresponding role priorities; sending the TIPC address information allocated to the slave network equipment to the slave network equipment; and sending the TIPC address information of the slave network equipment and the TIPC address information of the slave network equipment to the cloud server based on the communication connection established with the cloud server, so that the cloud server performs configuration management on the master network equipment and the slave network equipment.
