Problems solved by technology

[0002] The application of new technologies in automobiles puts forward higher requirements for the bandwidth of automobile networks, which promotes the explosive growth of bandwidth demand for automobile networks. However, traditional automobile networks have low bandwidth or high cost and poor scalability, making it difficult to meet the various needs of automobile manufacturers.
[0003] Ethernet was born early and has the advantages of mature technology, high bandwidth, low cost and strong scalability. It has been widely used before entering the automotive field. Due to the high transmission bandwidth of Ethernet, it leads to higher energy emissions. (Electromagnetic Compatibility) requirements are very strict, so that Ethernet has n
