Abstract
In general, this disclosure describes techniques that may allow detection of a missing control node on a ring network and selection of a single node on ring network to act as the control node. In one example, a method includes receiving, at a first node in a ring network, a data unit transmitted by a second node in the ring network, the data unit including an identifier that identifies the second node. The method further includes comparing the identifier of the second node to an identifier that identifies the first node, and automatically selecting one of the first node and the second node as a control node for the ring network based on the comparison.
