Flows installing
High level diagram of rerouting functionality. Flows will be rerouted when we receive next events:
- switch from flow path goes down
- switch through which flow was created before and this switch goes up again.
- link goes down
- link goes up and kilda performs checking whether flows witch DOWN state can be rerouted
Flows are restoring only during storm initialization and if there were any created flow before. After receiving these flows CacheBolt initiates flows restoring commands and then kilda creates/updates flow in regular way.
High level diagram of flow restoring functionality is provided bellow
