AI Technical Summary
Technical Problem
The timing issues in OVN caused the basic flow table to fail to be issued, resulting in traffic disruption.
Method used
By acquiring logical topology update events and adding them to the event queue, a scheduled task is triggered. When the scheduled time expires, the synchronization mechanism between the logical topology and the physical flow table is executed to update the physical network device configuration, thus avoiding the waste and instability of fixed-period synchronization mechanisms.
Benefits of technology
It enables more flexible topology change awareness, improves CPU performance and network stability, and ensures network traffic stability.

Abstract
This application provides an adaptive optimization method, apparatus, electronic device, and storage medium for incomplete flow tables. The method includes: acquiring an update logical topology event and adding the logical topology event to an event queue, wherein the event queue is used to record logical topology update actions; triggering a timed task in response to the logical topology event entering the event queue; and executing a synchronization mechanism from the logical topology to the physical flow table when the timed period expires, and updating the physical network device configuration. The adaptive optimization method, apparatus, electronic device, and storage medium described in this application avoids the problem of selecting a fixed period for executing the synchronization mechanism, more flexibly sensing topology changes, and performing synchronization after changes, thus avoiding the need to execute the synchronization mechanism during topology changes.
