March 2026: Delivered expanded test coverage for named ports in network policies and services for the ACI CNI plugin in noironetworks/aci-containers. Merged PR #1670 (commit f8a9155da85f725cc3d2b8cc4448f0be0866caf7) adding tests, configuration, and deployment scripts. No major bugs fixed this month. The work enhances reliability, accelerates validation of policy changes, and strengthens container networking quality.

In Nov 2025, delivered a feature in noironetworks/aci-containers to optimize intra-pod migrations by introducing a PlatformConfig Delete Notification Subscription from opflex-agent to host-agent. This enables host-agent to subscribe to PlatformConfig delete notifications, with opflex-agent updating a notification file on delete events. During a node-changed event, the host-agent reads this notification and, if the timestamp is within 2 minutes, treats the migration as intra-pod and skips DHCP release-renew steps. The change reduces DHCP churn, improves host-agent efficiency, and enhances migration scalability under node churn. Committed work is anchored by 77100407daa5cb43c138a28b5a830706e7d720c0 with a descriptive message detailing the notification-driven optimization.
