Redundancy through transmission media
If you use second-generation Ethernet router nodes (=RN2), the router
nodes first use the Ethernet connection and then the wireless connection
as backup.
If the WaveNet Manager detects when calculating the RingCast that
several RouterNodes reach each other wirelessly at the same time (in the
example "Initiator", 1, 2, 3, 4, 5 or 4a, 4b and 4c), it assigns exactly one
target partner to each RouterNode within this "radio cloud".
