  • Patent number: 10848428
    Abstract: The present application provides a method for dynamically allocating resources in an SDN/NFV network based on load balancing. For multimedia services with different demands, a virtual link mapping target, a constraint and a load state of a physical link are associated. A subtask is adaptively mapped to a network node according to the load state of the physical link. The method effectively distinguishes used resources and remaining resources of a physical node and a link to balance the load, and thereby improve the utilization of network resources and avoid occurrence of a local optimum or current optimum. The solution involves performing a subtask mapping to find a server node satisfying constraints for each subtask in a service request. The model for mapping the subtask is min T ? V ? ? Target 1 s . t . ? C 1 , C 2 , C 3 , C 4 .

  • Patent number: 10830044
    Abstract: A system and method for remotely locating a communication error support for hydraulic supports. The system includes a control panel, a support controller, a data converter, and two support drivers of the same type. Each support driver has two bus interfaces. The control panel transmits a control command to the data converter in a form of a WiFi signal. The data converter converts the WiFi signal into a message signal and transmits the message signal to the support controller. The support controller transmits the control command to the two support drivers, respectively. The support drivers transmit the command through CANH twisted pairs and CANL twisted pairs. When a bus for transmitting the command of a certain node has an error, the support controller calculates the fault node according to a formula n = p ? t 8 ? m , and feeds back the fault node onto the control panel.
