The Ethernet communication network is a high speed communication network providing a data transfer speeds of 100Mbps to 1Gbps, to support the on vehicle applications that require high data transfer rates such as over the air updates, driver assistance systems (Video data, radar data, ultrasonic data), multi media systems and connectivity to external devices. The GWM is the primary module within the Ethernet communication network and manages the distribution of data to the other connected modules on the network. Data from external sources (cloud based data) is received by the TCU and transferred over the Ethernet communication network to the GWM where it is distributed to the other modules connected to the Ethernet communication network and the vehicle communication networks. The modules connected to the Ethernet communication network are dependant on the vehicle configuration.
