Analysis and Optimization of Startup Performance of Ethernet Switches Based on Autonomous Platform

As a core component of information system interconnection, Ethernet switches directly affect the fast response capability of the system after power-on. The Ethernet switch software based on the autonomous platform is built based on the embedded Linux operating system. The system startup process includes four parts: BootLoader, kernel image loading, kernel startup, L2/L3 protocol, and application initialization. Based on the analysis of the startup process, the system optimizes the optimization strategy such as slimming, startup process reorganization, and SDK driver preloading, which greatly optimizes the startup performance of the Ethernet switch. The test results show that the Ethernet switch's Layer 2 data transmission recovery time is reduced from 103 seconds to 8 seconds, and the time is shortened by 92.23%.
