Summary

This chapter examined the nuances associated with ONS 15454 MSTP system design. Many factors can linearly and nonlinearly affect the system's performance. For simple point-to-point designs using fixed-channel OADMs, it is possible to quickly and effectively design a system manually. However, when the design becomes more complicated to include ring protection, ROADMs, mixed bit rates, and so on, it is more prudent and less time-consuming to employ the MetroPlanner design tool for system design.

This chapter presented only the basics for ONS 15454 MSTP system design. For complex scenarios, technical documentation for the ONS 15454 MSTP is available at Cisco.com for download and use.
