Network management device for automobile communications network provides selective disconnection of unrequired network segments

摘要

The network management device has a network manager providing a disconnection signal transmitted via the network (100), for switching network subscribers (21,31,33,41,43,51) into a non-communication mode, each subscriber re-activated via an information transmitted via the network. The latter is divided into network segments (20,30,40,50), separated from one another via at least one gateway (33,43), the network manager allowing disconnection of the network segments when non of the corresponding network subscribers are required by a different network segment.
