  • Patent number: 10911360
    Abstract: Some embodiments provide a method for managing traffic in a virtualized environment. The method, in some embodiments, configures multiple edge service gateways (ESGs) executing on multiple host machines (e.g., on a hypervisor) to use a same anycast inner internet protocol (IP) address and a same anycast inner media access control (MAC) address. In some embodiments, ESGs of a logical network facilitate communication between machines connected to the logical network and machines on external networks. In some embodiments, the method configures a set of virtual extensible local area network tunnel endpoints (VTEPs) connected to an ESG to use a same anycast VTEP IP address. The method, in some embodiments, configures a distributed logical router (DLR or DR) to send data packets with destinations outside the logical network from sources belonging to the logical network to the anycast VTEP IP address.

  • Publication number: 20200043303
    Abstract: An apparatus, such as a haptic-enabled device, and a method for providing boost protection logic are presented. The method comprises receiving, by a control circuit of the apparatus, a nonzero drive signal to be used by the haptic actuator to generate a haptic effect. The control circuit causes a first portion of the nonzero drive signal to be applied to the haptic actuator in a boost mode. The control circuit detects a boost duration exceeding a first defined time threshold, such as a boost timeout threshold, or detects an accumulated boost time exceeding the first defined time threshold. In response, the control circuit causes a second portion of the nonzero drive signal to be applied to the haptic actuator in an amplitude-limited mode.
