High Availability Management Network Requirements

The proNX Optical Director requires frequent updates on the current operating conditions of the ROADMs in your network in order to make the required decisions to maintain the optical performance of the managed device. This requirement for frequent updates drives the need for high availability and low latency in your management network (also known as the Data Communication Network or DCN).

In order to provide the reliability required, the DCN must be designed for high availability (HA). An HA system is intended for continuous operation and has redundant components and adequate backup and failover strategies.

You must connect both the proNX Optical Director and the devices that it manages to your highly available DCN. Refer to the proNX Optical Director Installation Guide for details on the high availability requirements for the proNX Optical Director.
