text: Figure 4-4 Communication example between pods 
  
  If both containers are running in the same node, the communication flow from one pod to 
  another uses the vethx interface from the same br0 interface of the node. 
  
  If the containers are running on different nodes, the flow of packets from one pod to another 
  use the vethX interface from the br0 ovs interface on different nodes.
