Development of Automotive Networking Topologies
Due to the ever more stringent cost, quality and time-to-market requirements, the
development of automotive vehicle networking systems has become a very chal-
lenging task. When specifying new networking systems or revising existing imple-
mentations, a major challenge is to validate that an implementation will work prop-
erly and robustly over the entire operating range. In-vehicle networking systems can
be divided into two domains:
•
Logical Network Architecture
: This domain deals with the actual data communi-
cation between ECUs.
•
Physical Network Architecture
: This domain deals with all aspects of the physi-
cal implementation of the in-vehicle network.
