Two Node

Overlapping

Rings

This topology connects two rings using a single fiber between two optical cards. At

each interconnecting node there are three optical ports: two east and a shared west.

Each ring shares the bandwidth of the west port.

Figure 9 Two Node Overlapping Rings

The Traverse supports the following protection schemes in two node overlapping ring

interconnections:

• STS and VT 1+1 path protection

• High order and low order SNCP

Two Node

Interconnected

Rings

This topology uses four trunk ports in each node to connect two separate rings. The east

and west port of each ring must be on two separate cards.
