Abstract
Described are edge devices configured to perform operations to migrate a workload. These operations comprise: receiving a migration trigger comprising an indication of a migration of a workload from a source edge device; establishing a secure communication channel with the source edge device; receiving a network state for the workload from the source edge device; quiescing a datapath for processing flows associated with the workload; receiving incremental deltas comprising changes to the network state from the source edge device; updating the datapath for processing flows associated with the workload based on the received incremental changes; providing, to the source edge device, a request for a final synchronization; receiving, from the source edge device, a final synchronization delta comprising incremental information for the network state as modified since the most recently received incremental change; and removing the quiescing of the datapath to facilitate use of the network state.
