Nov 1, 2025November 2025 (2025-11): Focused on improving SR-SIM observability, reliability, and network correctness within srl-labs/containerlab. Delivered container labeling to identify SR-SIM root nodes, addressed a critical networking offload issue, and hardened interface enumeration to tolerate partial failures. These changes reduce mean time to diagnose issues, improve scalability for distributed SR-SIM topologies, and strengthen overall deployment stability. Technologies demonstrated include container orchestration visibility, Linux networking (veth), TX checksum offload considerations, and robust error handling, with clear commit traceability across changes.

Apr 1, 2025Month: 2025-04. Focused on expanding configurability and user guidance for the containerlab VS Code extension. Key deliverable: a new Telnet port configuration option (containerlab.node.telnetPort) documented in the extension docs, enabling users to specify the Telnet port when connecting to containers. This aligns with improving flexibility in container access and onboarding for Telnet-based workflows. No major bugs were reported this month; effort concentrated on design, documentation, and safe deployment of the new setting.
