Scaling edge services with minimal disruption
Some embodiments provide a method for forwarding data messages between edge nodes that perform stateful processing on flows between a logical network and an external network. At a particular edge node, the method receives a data message belonging to a flow. The edge nodes use a deterministic algorithm to select one of the edge nodes to perform processing for each flow. The method identifies a first edge node to perform processing for the flow in a previous configuration and a second edge node to perform processing for the flow in a new configuration according to the algorithm. When the first and second edge nodes are different, the method uses a probabilistic filter and a stateful connection tracker to determine whether the flow existed prior to a particular time. When the flow did not exist prior to that time, the method selects the second edge node for the received data message. |

The stator has multiple phase legs, each respective one of which includes a single phase lead connected to two or more parallel stator windings. The stator thus has multiple phase leads collectively conducting phase currents. A rotary output member is connected to the rotor and connectable to a load. A traction power inverter module (TPIM) is electrically connected to the phase legs. Current sensors collectively measure the phase currents. Each respective current sensor is connected to a different phase lead. A controller in communication with the current sensors and the TPIM, in response to a commanded current and the measured phase currents, detects a threshold variation in the measured phase currents indicative of a phase current imbalance fault, and selectively changes a thermodynamic state of the electrified powertrain in response to the fault. |

Stator and brushless motor and motor actuator using the stator
A stator has a core, an insulating member that covers the core, windings that are wound around the insulating member, and conductive members that supply drive power to the windings. The conductive member has a joining part that contacts a lower surface of the insulating member, an insertion part that rises axially upward from one end of the joining part, and a board connection part that descends axially downward from the other end of the joining part. The insertion part penetrates through the insulating member and protrudes at the top of the stator, where it is connected to a coil end. The board connection part is fixed, by a method such as press-fitting, to a circuit board on which a Hall element or the like is mounted. |
