초록

Recently, as the demand for technology related to autonomous vehicles increases, various standards have been established in order to meet these requirements. Among them, IEEE 802.3ch is establishing a PHY layer standard to support In-Vehicle Network's gigabit Ethernet. Among the standardization issues of IEEE 802.3ch, there is an asymmetric data transfer issue. This is an issue to discuss how to cope when the differences in data transmission rates are different between up and down directions. In this paper, we propose a link speed switching method using auto-negotiation as a way to provide solutions to these issues. This has the advantage of preventing data loss when switching the link speed. There is also a cost advantage because there is no need for new development.
