Bypassing a load balancer in a return path of network traffic
Some embodiments provide a method that allows a first data compute node (DCN) to forward outgoing traffic to a second DCN directly in spite of receiving the incoming traffic from the second DCN through a load balancer. That is, the return traffic's network path from the first DCN (e.g., a server machine) to the second DCN (e.g., a client machine) bypasses the load balancer, even though a request that initiated the return traffic is received through the load balancer. The load balancer receives a connection session request from a client machine to connect to a server. It identifies a set of parameters for the connection session and after selecting a server for the connection, passes the identified set of parameters to a host machine that executes the server. The server establishes the connection session directly with the client machine based on the identified set of parameters. |

Delay-based tagging in a network switch
A network device organizes packets into various queues, in which the packets await processing. Queue management logic tracks how long certain packet(s), such as a designated marker packet, remain in a queue. Based thereon, the logic produces a measure of delay for the queue, referred to herein as the “queue delay.” Based on a comparison of the current queue delay to one or more thresholds, various associated delay-based actions may be performed, such as tagging and/or dropping packets departing from the queue, or preventing addition enqueues to the queue. In an embodiment, a queue may be expired based on the queue delay, and all packets dropped. In other embodiments, when a packet is dropped prior to enqueue into an assigned queue, copies of some or all of the packets already within the queue at the time the packet was dropped may be forwarded to a visibility component for analysis. |

Rotating electrical machine
A rotating electrical machine includes a rotor and a magnet unit. The rotating electrical machine also includes a cylindrical stator and a housing. The stator is equipped with a stator winding made up of a plurality of phase windings. The stator is arranged coaxially with the rotor and faces the rotor. The housing has the rotor and the stator disposed therein. The rotor includes a cylindrical magnet retainer to which the magnet unit is secured and an intermediate portion which connects between a rotating shaft of the rotor and the magnet retainer and extends in a radial direction of the rotating shaft. A first region located radially inside an inner peripheral surface of a magnetic circuit component made up of the stator and the rotor is greater in volume than a second region between the inner peripheral surface of the magnetic circuit component and the housing in the radial direction. |

Rotary electric machine unit
A rotary electric machine unit includes a rotary electric machine, where a protruding portion extending in an axial direction from a one end side cover portion toward the rotary electric machine is formed at a position below a rotation axis of the rotary electric machine and overlapping with the rotary electric machine. A refrigerant flow lower surface formed on a tip end side of the protruding portion and extending in the axial direction, and a recessed surface adjacent to a base side end portion of the refrigerant flow lower surface and extending in the axial direction at a position recessed upward than the refrigerant flow lower surface are formed below a center of the protruding portion in the upper-lower direction. The refrigerant flow lower surface of the protruding portion is arranged such that an axial central portion overlaps the rotary electric machine in the axial direction. |
