Management system, virtual communication-function management node, and management method for managing virtualization resources in a mobile communication network

The semiconductor device including: two fins having rectangular parallelepiped shapes arranged in parallel in X-direction; and a gate electrode arranged thereon via a gate insulating film and extending in Y-direction is configured as follows. First, a drain plug is provided over a drain region located on one side of the gate electrode and extending in Y-direction. Then, two source plugs are provided over a source region located on the other side of the gate electrode and extending in Y-direction. Also, the drain plug is arranged in a displaced manner so that its position in Y-direction may not overlap with the two source plugs. According to such a configuration, the gate-drain capacitance can be made smaller than the gate-source capacitance and a Miller effect-based circuit delay can be suppressed. Further, as compared with capacitance on the drain side, capacitance on the source side increases, thereby improving stability of circuit operation.

Semiconductor device

In an update management system including a plurality of servers executing a communication service, a server not connected to a network in which a new version of an application is operated is generated in parallel with a server in which an old version of the application is operated, and old and new correspondence data between an old version server and a new version server is generated and used to execute switching from the old version server to the new version server in a flow on the network and to execute switching-back to the old version server by referring to the old and new correspondence data at the time of occurrence of fault in a new version.
