RSTP uses a mechanism to calculate a spanning tree in a redundant connected network, each network device searches for the
shortest path to the root bridge, offers this path to other to other devices, and administers which path can be used as an
alternative path. Ports are assigned this role.
If a root port fails, an alternate port is used as the new root port. If there is no alternate port available, a new spanning tree is
calculated.
RSTP is useful within OMNEO when connecting OMNEO devices redundantly (for example in a daisy chain or when
connecting OMNEO devices to different switches for a redundancy scheme to limit the audio loss to less than 100ms)
IMPORTANT: If devices do not support RSTP, chains of device may not be connected redundantly. This means audio
is lost for a longer duration of time if the link fails inside the daisy chain. When the link is restored, a
loop is created for a few seconds. The loop created could flood the local network.
