Networks for Data Communication

Specialized internal communications networks interconnect components inside automobiles, buses, trains, industrial or agricultural vehicles or aircrafts. Special requirements for vehicle control such as assurance of message delivery, of non-conflicting messages, of minimum time of delivery, of low cost, and of EMF noise resilience, as well as redundant routing and other characteristics mandate the use of less common networking protocols. Protocols include Controller Area Network (CAN), Local Interconnect Network (LIN),  Media Oriented System Transport (MOST), FlexRay and others. Also conventional computer networking technologies such as Ethernet and TCP/IP are established in automotive engineering by now. For aircrafts Vector offers implementations of AFDX and ARINC 429.


CAN (Controller Area Network) technology is used in the automotive, industrial automation and aerospace industries, in which OEMs and suppliers are confronted with many types of challenges. Vector supports you with professional CAN/CAN FD software tools, network interfaces, AUTOSAR basic software and worldwide services.

Automotive Ethernet

Ethernet is used in vehicles in various use cases: transmission of large amounts of data, e.g. for autonomous driving, driver assistance systems (ADAS), infotainment and data backbones. Furthermore Ethernet is used for measurement and calibration, diagnosis via DoIP and communication of electric vehicles with the charging infrastructure.
