Using Ethernet Technology for In-Vehicle´s Network Analysis

During the last years, Ethernet increasingly became the most extensively used local area networking (LAN) technology. It became also attractive for several other fields of application like industry, avionics, automotive and telecommunication. The prolonged application of this technology is principally due to its considerable assets like reduced cost, expandability and flexibility. However, Ethernet has been improved to fulfill with the specific conditions of several application fields, mainly in automotive context, is our first purpose. This paper provides firstly a general overview of Ethernet in the automotive field (especially on diagnosis process) comparing it to earliest automotive networks. Then, we will present CableFish, our optimized and high performance network analyzer. CableFish gives a real time analysis for all packets circulating between several ECUs (without loss) and allows in-car diagnosis due to the newly added HSFZ protocol.
