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.

Abstract: Described are platforms, systems, and methods for upgrading firmware on a programmable input output (IO) device. In one aspect, a method executed by the programmable IO device comprises: receiving, from a north-bound entity, a request to upgrade firmware installed on at least one CPU core; disabling flow-miss traffic to the at least one CPU core; redirecting the flow-miss traffic to an off-box service; providing a configuration for the programmable IO device to the off-box service; redirecting traffic to the off-box service; upgrading the firmware installed on the at least one CPU core; upgrading at least one program running in the data plane; reprograming a forwarding state provided by the off-box service; disabling the redirection of the traffic to the off-box service; and providing, to the north-bound entity, a notification indicating a completion of the upgrade.
