About Ring Topologies
A ring topology is a network of three or more nodes each of which connects to two other nodes to form a "ring". Ring topologies support splitter protected, line card protected, and unprotected configurations. On a ring, traffic is transmitted in both directions from each node; traffic is received from only one direction. In case of a fiber failure, the node switches over to receive traffic from the other direction.
The Cisco ONS 15540 supports hubbed ring and meshed ring topologies.
Note
Hubbed Ring Topologies
In a hubbed ring topology, all channels originate and terminate on the hub node (node1 in Figure 8-1). The other nodes on the ring, sometimes called satellite nodes, add and drop one or more channels. The added and dropped channels terminate at the node, while the channels that are not being dropped (express channels) are passed through optically, without being electrically terminated.
Figure 8-1 Hubbed Ring Topology Example
For more information on hubbed ring topologies, refer to the Introduction to DWDM Technology document and the Cisco ONS 15540 ESP Planning and Design Guide.
Meshed Ring Topologies
A meshed ring is a physical ring that has the characteristics of a mesh. Figure 8-2 shows an example of this type of configuration, which is sometimes called a logical mesh. While all traffic travels around the physical ring, nodes 1 and node 3 share band B (channels 5-8), and nodes 3 and node 4 share band D (channels 29-32). Hence there is a logical mesh overlay on the ring.
Protection options and optical link loss budget considerations are the same as in a hubbed ring configuration.
Figure 8-2 Meshed Ring Topology Example
For more information on meshed ring topologies, refer to the Introduction to DWDM Technology document and the Cisco ONS 15540 ESP Planning and Design Guide.
Configuring a Hubbed Ring with Splitter Protection and OSC
Figure 8-3 shows an example topology of a three-node hubbed ring. Node 1 is the hub configured with band A through band D (channels 1-16). Node 2 adds and drops band A (channels 1-4), node 3 adds and drops band B (channels 5-8), node 4 adds and drops band C (channels 9-12), and node 5 adds and drops band D (channels 13-16). The transponders carry Gigabit Ethernet traffic.

Node 1
Figure 8-4 shows how the modules are installed in the shelf for node 1 in the example network shown in Figure 8-3. The shelf is populated for the 16-channel splitter protected hub node. Splitter protected line card motherboards are installed in slots 2-5, and the 16-channel mux/demux modules are used in the east and west mux/demux slots.

Figure 8-5 shows how the 16-channel mux/demux modules are cabled for the hub node in the splitter protected hubbed ring shown in Figure 8-3.

Line card protection requires a different shelf and CLI configuration from splitter protection. The following sections describe an example based on the hubbed ring topology shown in Figure 8-3.

The line card motherboards in slots 2-5 are west motherboards, corresponding to the 16-channel mux/demux module in the west mux/demux slot; the line card motherboards in slots 8-11 are east motherboards, corresponding to the 16-channel mux/demux module in the east mux/demux slot.

Configuring a Meshed Ring with Line Card Protection and OSC
Line card protection requires different shelf and CLI configuration from splitter protection. The following sections describe an example based on the meshed ring topology shown in Figure 8-24.
Node 1
Figure 8-38 shows the shelf configuration for node 1 using line card protection in the example meshed ring shown in Figure 8-24. Slots 2, 5, and 8 use west line card motherboards, corresponding to the add/drop mux/demux modules in the west mux/demux slot; slots 3, 4, and 10 use east line card motherboards, corresponding to the add/drop mux/demux modules in the east mux/demux slot.

Figure 8-39 shows how the 4-channel mux/demux modules are cabled for node 1 in the line card protected meshed ring shown in Figure 8-24.
