RSTP in Structured Wiring Configurations

RSTP may be used to construct structured wiring systems where connectivity is maintained in the event of link
failures. For example, a single link failure of any link between A and N in
bridges 555 through 888 connected to the network.
Figure 14: Example - Structured Wiring Configuration
To design a structured wiring configuration, do the following:
1. Select the design parameters for the network.
What are the requirements for robustness and network failover/recovery times? Are there any special
requirements for diverse routing to a central host computer? Are there any special port redundancy
requirements?
