  • Publication number: 20250055799
    Abstract: The disclosure relates to a method, an apparatus for traffic congestion control, a computer-readable medium, and an electronic device. The method includes: allocating a network card bandwidth to a virtual machine on a same physical machine, where the network interface of the virtual machine is used for transmitting traffic of first and second transmission protocols; for any virtual machine on the physical machine, dividing a total bandwidth of the virtual machine into a first bandwidth, a second bandwidth, and a buffer bandwidth, where the first bandwidth is used to transmit traffic of the first transmission protocol, and the second bandwidth is used to transmit traffic of the second transmission protocol; and reallocating a bandwidth of the first and second transmission protocols based on the actual bandwidth used by the first and second transmission protocols.

  • Patent number: 12021346
    Abstract: A multi-module fiber laser capable of monitoring abnormalities of optical modules in real time. In the multi-module fiber laser, the CAN bus is employed to directly obtain whether each of the slave control modules or the master control module is in normal working condition, so that the CAN bus is at the status level corresponding to whether all modules are in normal working state, namely, the CAN bus that is configured to transmit the light control signal issued by the master control module. The status level of the slave control module or the combiner module is also transmitted via the CAN bus, so that all the slave control modules can quickly put themselves in the corresponding working state according to the status level of the CAN bus.
