This course focuses on analyzing the performance of two distinct datapaths for Open vSwitch in the Linux kernel: ovskdp and TC DP. The goal is to identify bottlenecks in the TC SW dp and propose improvements to enhance performance. Students will learn to evaluate datapaths using the perf tool, extend the existing act infrastructure, and optimize TC SW performance by completing RCU-ification of TC actions. The teaching method includes performance evaluation, proposing enhancements, and comparing with custom eBPF programs. This course is intended for individuals interested in Linux kernel development, network performance optimization, and datapath analysis.
