Network monitoring places additional load on the Data Communication Network (DCN). Monitoring 200 NEs typically requires around 1 Mbit/s of DCN bandwidth.

To support more than 200 NEs, it is recommended to optimize the DCN design in the network core to prevent bottlenecks. For example, using a VPLS between ABR nodes, connected to an EROP1 router unit at the gateway nodes to the FOXMAN-UN, can improve network scalability and performance.

For large networks, a good practice is to start Health Monitoring with 50 NEs, and then gradually increase the number as needed.
