Adaptive stateless load balancing
In general, techniques are described for load balancing, with a service node, packet flows using stateless load balancing that adapts to server failure to provide flow affinity to initially selected servers for the duration of respective flows. In one example, service node device applies stateless load balancing to packet flows to distribute the flows among a plurality of servers. The service node determines a failure of a failed server and then receives an initial packet of a packet flow from the packet flows and forwards the initial packet to an active server. The service node generates a mapping of the packet flow to the active server, determines a recovery of the failed server, receives a subsequent packet of the packet flow, and forwards the subsequent packet of the packet flow to the active server based at least on the mapping of the packet flow to the active server. |

The diode region includes a plurality of first conductivity type anode layers exposed to a surface of the semiconductor substrate and separated from each other. The IGBT region includes a plurality of first conductivity type body contact layers that are exposed to the surface of the semiconductor substrate and separated from each other. The anode layer includes at least one or more of the first anode layers. The first anode layer is formed in a position in the proximity of at least IGBT region, and an area of a plane direction of the semiconductor substrate in each of the first anode layers is larger than the area of a plane direction of the semiconductor substrate in the body contact layer in the closest proximity of the diode region. |
