The automotive industry requests different communication technologies for in-vehicle networking. It is a challenge to integrate different bus systems and networks from different implementors. Conformance and interoperability testing is only successful, if the tests are standardized. The paper describes the actual status of automotive-oriented communication technologies submitted for international standardization. It discusses the challenges and the pros and cons of standardized solutions ("frozen" technology). Another topic are the gaps still exisiting in standardization, e.g. gateways, middleware, etc. The presentation will also address the administrational and bureaucratic hurdles in the standardization bodies. Of course, there is a survey provided on the currently networks under standardization and those which under submission. This includes an attemp to classify in-vehicle networks and to evelaute the overlapping.
