Add trafficControlController to handle TrafficControl requests #3487

wenqiq · 2022-03-19T13:25:30Z

The Antrea Agent is responsible for realizing the traffic control request.
It watches the TrafficControl resources from the K8s API server and manages the container traffic with OpenFlow rules. Specifically, the agent executes the following steps for a TrafficControl resource:

Use label selectors to filter Pods running on this Node.
Translate the selected Pods to OVS ports, which will be used to filter traffic that should be mirrored or redirected.
Translate the target device to the OVS port, which will be used as the target port the traffic should be mirrored or redirected.
Install OpenFlow rules calculated using the above arguments.
