Evaluation of Latency Time for Class C High Speed LAN Protocols 940363
The latency time of class C in-vehicle LAN systems was evaluated in order to analyze the difference in latency time between the non-destructive CSMA/CD (CSMA/CD+NDA) and the token passing selected as the high speed LAN protocols. The evaluating method was constructed by combining simulation and an analysis equation.
As a result, the limits of traffic volume available for vehicle application were approximately 80 to 90 % for the CSMA/CD+NDA and 30 to 40 % for the token passing at a transmission rate of 1 Mbps.
