May 1, 2026May 2026 (NVIDIA/doca-platform): Hardened network isolation for virtual networks by adding automated validation for same-node, cross-subnet traffic and aligning test fixtures with mainline. Implemented a dedicated test case to verify that traffic between subnets on the same node is correctly isolated, preventing unintended communication. Also bumped the VPC reference in tests to the latest core, improving reliability and maintainability of the suite. These changes reduce risk of network policy regressions, strengthen isolation guarantees for multi-tenant environments, and enable faster, safer releases through expanded automated validation.

Mar 1, 2026Month: 2026-03 | NVIDIA/doca-platform Summary: Open vSwitch (OVS) VPC test resilience improvements were delivered to stabilize the VPC test suite and reduce flakiness. The changes remove DNS dependency for SSH, extend SSH connect timeouts and keep-alives, and introduce SSH retries with exponential backoff. These updates contribute to more reliable test results and faster feedback in CI, strengthening confidence in platform readiness.

Jan 1, 2026January 2026 monthly summary for NVIDIA/doca-platform: Delivered API simplification for bridge management by normalizing the Bridge Interface Type. Removed the interfaceType parameter from AddBridge and set it to a constant value of 'internal' for all bridges, reducing API surface, preventing configuration errors, and improving consistency across deployments. This change enhances maintainability and supports future internal networking optimizations. No major bugs reported; all work concentrated on feature refinement with clear business value.

Jul 1, 2025Month 2025-07 — NVIDIA/doca-platform: Key features delivered and major fixes focused on improving network reliability and performance. VPC network stability fix implemented by simplifying the network chain (remove ovn-vtep-patch interface and associated bridge) and introducing a single chain between p0 and br-ovn-ext. Added ovnvtep internal port to br-ovn-ext and assigned a VTEP IP to resolve low bandwidth and asymmetric speed issues. Commit reference: 1ddd77a640dfd609ffa013d01e2eaba7421feedd.
