Setting up Sub-Rings has the following advantages:
X Through the coupling process, you include the new network segment in
the redundancy concept.
X You can easily integrate new company areas into existing networks.
X You easily map the organizational structure of a company in the network
topology.
X As an MRP-Ring, the switching times of the Sub-Ring in redundancy cas-
es are typically <100 ms.
The following graphics show examples of possible Sub-Ring topologies:
