Apr 1, 2025Month: 2025-04 | Repository: sonic-net/sonic-mgmt 1) Key features delivered - Implemented and validated a fix for RDMA test packet loss calculations in VOQ chassis environments by differentiating ingress and egress drops based on chassis type (VOQ vs non-VOQ). This ensures accurate loss percentage reporting in VOQ environments. (Commit: 7c21718fb2ce524036eca5220c8773c2dce5cda0) 2) Major bugs fixed - RDMA Test Packet Loss Calculation for VOQ Chassis: corrected packet drop calculation logic to reflect VOQ-specific semantics, preventing misreporting of loss rates. 3) Overall impact and accomplishments - Improves reliability and trust in performance tests for VOQ-based deployments; reduces false positives/negatives in loss measurements; aligns test results with real network behavior; supports ongoing VOQ adoption. 4) Technologies/skills demonstrated - RDMA testing, VOQ vs non-VOQ chassis differentiation, test framework instrumentation, patch management, commit-level traceability.
