January 2026 monthly summary for sonic-swss focusing on feature delivery, bugs fixed, and business impact. Key telemetry enhancement delivered for gbsyncd, with FEC histogram polling, rate and BER computation, and gearbox counters configuration. Refactored port_rates.lua to compute rates (bps/packet counters) and BER, with GB_COUNTERS_DB considerations. Enabled port_rates.lua on GB_COUNTERS_DB and ensured telemetry scripts track gearbox counters for improved observability and service reliability.

November 2025 performance highlights for sonic-buildimage. Key feature delivered: gbsyncd container support for Agera2 external gearbox devices, enabling containerized driver control and seamless integration with the Agera2 hardware stack. This work included the addition of a gbsyncd-agera2 build file, Dockerfiles, and a startup script to ensure reliable initialization across environments. Impact: Enables scalable, consistent deployment of Agera2-related gear, reducing manual setup and accelerating integration into production pipelines. Technologies/skills demonstrated: Docker/containerization, build automation, device-driver packaging, and Debian-based packaging considerations. Note: No major bugs fixed in scope for this period; primary focus was feature delivery and infrastructure improvements.
