The German project simTD1 is the first large field test for cooperative vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication systems in Europe and it consists of over 400 cars and over 100 roadside units (RSU). To manage that number of RSU new concepts are needed to ensure high system availability. The system management has to provide the following features: basic configuration, installation and maintenance of applications as well as fault management. Secure and reliable data transfer and a framework for applications is the base for the tasks mentioned before. Additionally an administration and monitoring interface for operators needs to be considered.
