2.5.5 Multiple Master Ring
This is another form of ring topology, where there are multiple masters on the ring, and
these masters have to receive data as well as transmit data to the next master. In the most
complex case, each node is a master, which means that it receives data from the previous
master and sends data to the next master. Flow control is not allowed in this topology for
rings above two nodes, and the data cannot be passed through masters unless control
guarantees that there is at least one source-only node on the ring and that no two masters will
transmit at the same time. Single master rings should temporarily become multiple master
rings when switching loop masters.
