우선 순위 트래픽을 고려한 자동차 이더넷 토폴로지 최적화

다국어 초록 (Multilingual Abstract)

In current vehicles, a large number of control units are connected by several automotive communication buses. Ethernet is currently explored as the upcoming network for an automotive industry. It offers higher performance and flexibility over traditional control bus systems such as CAN and FlexRay.
For applying the ethernet network to a vehicle, there are many possible choice for topology configuration way. In previous research, they propose to find the best distribution of the industrial devices on a switched Ethernet architecture with GA techniques. But the priority issue is one of the main factor for topology optimization in car ethernet network.
In this paper, We propose new fitness evaluation way to improve ethernet-based car network performance. Our objective is to optimize the redundant hierarchical network with considering priority.
