Troubleshooting Software-Defined Networks requires a structured approach to detect mistranslations between high-level intent (policy) and low-level forwarding behavior, and a flexible on-demand packet tracing tool is highly desirable on the data plane. In this paper, we introduce a Layer 2 path tracing utility named PathletTracer. PathletTracer offers an interface for users to specify multiple Layer 2 paths to inspect. Based on the Layer 2 paths of interests, PathletTracer then accounts paths… CONTINUE READING
