  • Patent number: 11418382
    Abstract: A method for cooperative active-standby failover between service routers based on health of services configured on the service routers is presented. In an embodiment, a method comprises determining, by a first service router (“SR”) of a SR cluster, a plurality of aggregate score values for a plurality of SRs of the SR clusters. The SR cluster comprises the first SR which is active, and a second SR. An aggregate score value, of the plurality of aggregate score values, indicates health of one or more services configured on a SR. The method further comprises determining, based on the plurality of aggregate score values, whether the first SR, of the SR cluster, is healthier than the second SR. In response to determining that the first SR is healthier than the second SR, the first SR continues to operate in the active mode; otherwise, the first SR switches to a standby mode.

    Abstract: A power drive circuit includes a power conversion module, a plurality of gate drivers, a waveform processing unit, a control unit, a weighting unit, and a comparator. Each gate driver includes a drive resistance setting value. The waveform processing unit outputs a current absolute value waveform of an AC power. The weighting unit generates a trigger voltage. When the comparator determines that the current absolute value waveform is greater than the trigger voltage, the comparator outputs a slew rate control signal to each of the gate drivers. When the gate driver receives the slew rate control signal, each of the gate drivers decreases the drive resistance setting value of the gate driver.

  • Publication number: 20220141155
    Abstract: Some embodiments provide a method for handling failure at one of several peer centralized components of a logical router. At a first one of the peer centralized components of the logical router, the method detects that a second one of the peer centralized components has failed. In response to the detection, the method automatically identifies a network layer address of the failed second peer. The method assumes responsibility for data traffic to the failed peer by broadcasting a message on a logical switch that connects all of the peer centralized components and a distributed component of the logical router. The message instructs recipients to associate the identified network layer address with a data link layer address of the first peer centralized component.
