Abstract

To address the technical challenges of data transmission efficiency in the software design phase of CAN-Ethernet gateway, an optimization scheme for user-space protocol stacks based on DPDK (Data Plane Development Kit) technology is proposed. Traditional kernel-based packet processing methods incur significant performance overhead due to frequent interrupts. By introducing DPDK technology, packet processing is done directly in user space, avoiding the performance losses caused by interrupts. This study designed a DPDK user-space protocol stack based on the Loongson 2k1000LA development board and LoongOS operating system, implementing support for ARP, ICMP, and UDP protocols. Performance comparison tests with traditional kernel protocol stacks show that this solution significantly improves gateway data throughput, reduces data processing latency, and lowers CPU utilization, thereby enhancing the overall performance of the CAN-Ethernet gateway. In addition, KNI (Kernel NIC Interface) technology is used to handle special packets, ensuring system flexibility and scalability.
